A couple of J30 keyless entry questions

[Infinitiguy19]

Whats up guys this is my first time posting a topic here. But from what I can tell you guy are far nicer than the Q guys (Me included ).

But the questions:

1. When you press the unlock button ONCE on the remote does the drivers door open only?

2. How far does the keyless remote really work, because what it says on paper is sometimes never really true.

3. How hard is it to remove the door lock timer and keyless entry control unit?

I had more questions but I already answered them.

I ask these questions because I own a 1993 Q45 and it has no keyless entry. So I was looking in the Infiniti Parts forum and I looked some guy J30 that he was parting out. And I thought to my self the 1993-1997 J30 has keyless entry but NO BCM*....DING DING DING, JACKPOT. And ever since then I have been studying the wiring diagrams for the anti-theft and Multi-Remote Control Unit. Needless to say that a 1992-1993 Q45 can have keyless entry from a J30.

I bet some of you are saying why would you want it. The reason is because some people who own a car take it or parts of it for granted. And:

1. I want to keep my car as OEM as possible because I hate aftermarket stuff.

2. I want to keep the costs low, but really that's just the perk of #1 above...Only in this case though.

3. I want to have video, pictures and wiring diagrams and what ever else I can make should there be a problem with this system in the future.

Now the boys in the Q45 forum one especially tries to find all the faults in my idea's, You know who you are. And I originally though of disbanding from NICO because of this one ***hole. But I come to realize after many hours of reviewing wiring diagrams that its not worth leaving because of one guy. So I can go back and rub this in there face.

So in the end my Q will be like America in that it will have modifications (People) from all different sorts of cars (nationalities).

J30 guys ROCK!!!

1. When you press the unlock button ONCE on the remote does the drivers door open only?

Yes

2. How far does the keyless remote really work, because what it says on paper is sometimes never really true.

Originally, you could be 2-3 cars away and open the doors, trunk etc. Over time that has degraded, even though I have changed the battery in the remote. Currently, I have to basically be beside the car to open the door or pop the trunk with the remote.

3. How hard is it to remove the door lock timer and keyless entry control unit?

I think the door lock timer is under the dash. I've never had to remove it, but I hear its a real PITA. I don't know about the keyless entry control unit.

[Infinitiguy19]

This is the best respoce I go on NICO so far no joke. Reason being because I want to get this done to my car.

And if any of you J30 guys are interested I think you can install one of those control units that control the windows and sun roof through the remote. I am not 100% certain on this because I am not a master alarm/radio installer or electrician. But I am going to check with someone who is and make sure.

Now if any of you guys are interested look at pins #8 and #11 on the door lock timer and pins #14 and #16 on the multi-remote control unit.

And another question: Do any of you guys have the key FOb that beeps, and if so does it make any differnce or is it noticible?

I ask the above because those remotes are no longer avalible and the part numbers supercede to the remote without that feature. Damn Nissan for cheaping out.

You guys are awesome and I hope I can return the favor.

None of our key fobs beep. The car doesn't honk when the alarm is engaged. The only thing that happens is that you hear the doors lock and the security light on the dash comes on to indicate the alarm is engaged.

The J30 fob cannot close the sunroof. The only car I owned where the key fob could close the sunroof was a VW, but only if you held the lock on the fob down long enough.

[Infinitiguy19]

NOTE : The "beep" function in some Infiniti keyless remote controllers was deleted during the period 3/94 to 5/94,depending upon the model. After 6/1/94 production, no Infiniti remote controllers have a "beep". If a customer requests aremote that "beeps" when the buttons are pressed, the replacement remove controller should not be charged to Warranty.

I was saying that there could be a possiblity of adding a aftermarket control module to make the windows and sunroof work with the lock and unlock buttons.

But when the car is unlocked does the interior light go on?

When the car is locked the hazzard lights should flash and if not disabled by holding the lock and unlock button the hor should honk when the car is locked. And when you hit the lock button again the hazzards should flash twice to tell you that the car is already locked.

The owners manual for the Q45 and J30 is the same on this subject, because in the J30 owners manual it says that the windows are also controlled by the remote control.

[driverdriver]

Yes the hazard lights do come on, I neglected to mention that. The car has never honked, when the alarm has been engaged. I've had the car basically from new.

My windows are not controlled by the remote, maybe they where controlled in the later years?

[Infinitiguy19]

Ifyou want you can try holding the lock and unlock button at the same time and see if that enables it and vise versa to disable it.

I can't believe I am so excited to have something that is so outdated to some people (in the Q forum).

[Infinitiguy19]

If you want you can try this to increase the range: http://www.youtube.com/watch?v=8f-g2W4ZoEw

I would just sand the antenna down and put it back together and see what that does.

I plan on buying a brand spanking new remote for my car.

[Infinitiguy19]

Hey I have a question for you all once more:

When you press the trunk unlock button the key fob...Then when the trunk is closed do you hear the door locks locking up?

I ask because the service manual is a CLUSTERf*** of errors.

In a nutshell it says that a alarm disarm signal is sent to the alarm control unit from the key less entry control unit. Then nearly the same time a lock signal is sent from the key less entry control unit to the door lock timer.

So that would mean the trunk would open but when you close it after 30-40 second the alarm would be activated so wouldn't that set it off?

[jspout]

Hey Paul, Yes J30 owners are way cooler than Q owners! Ha. If you want, I can test some of this stuff for you before i disable and remove it. I know the alarm works as i have set it off a couple of times. I just need a battery for the remote. Call me tommorow in the morning. Lance

[Infinitiguy19]

Hey yet another question: When you lock and unlock the car do the hazards flash?

[jspout]

I thought I had better share my parts experience on these keyless remote parts. Most of these parts are pretty easy to get to and remove, but identifying and locating them was tricky. The main part in the system is in the trunk on the driver side. It is directly behind the tool compartment. The Door Lock timer is a grey 2x3 inch box that is mounted on a bracket near the right side of the ebrake pedal. it only had one screw holding the bracket, but the box itself can be removed from the bracket without removing the screw. There is 2 connectors, one white and one black. There is a brown and a blue diode near the top of the gas pedal. The Brown one is the one you need. The other diode needed is also brown, is powered and sits directly to the right of the EC brain on the passenger kick pannel. You have to remove the brain to get to it, it is hidden. Also, removing this diode and the engine will no longer run. The antenna is a grey wire on the right side of the trunk that runs up into the cab and is connected to a small antenna on the back window and is connected only by solder. Nothing too difficult, just tough to locate.

Hey yet another question: When you lock and unlock the car do the hazards flash?

I found the answer to this one.

What I am confused about now is whether the horn honks when locking and unlocking the car, can anyone confirm or deny this?

If your doesn't do it then hold down the "lock" and "Unlock" button at the same time for 2 seconds. The horn should honk but if not lock or unlock the car and see what happens.

Please somebody answer this for me.

[Infinitiguy19]

C'mon guys I really need help on this one because I have read every wiring diagram, read every page of the service manual on this basically done all I can. I think I have done everything short of opening the Multi-Remote Control unit up and reverse engineering it.

I promise the above post is the last question.

[driverdriver]

My horn has never honked when locking or unlocking the doors. The only thing that happens is the hazzards flash.

[Infinitiguy19]

Right I remember you saying that in the begging of the topic and I thank you for your response then and now. But do you mind trying out what pressing the "lock" and "unlock" button together for 2 seconds yields?

I see no way this to be possible in the service manual but it has been WRONG o so many times. And this will be a big deal if I am to make sure I can control the sun roof and windows, Because if the horn honked every time the alarm was armed or disarmed the windows and sun roof would close and open respectively.

[2brokey]

No, the horn never honks when you do that. If you want a setup that controls the windows with the factory remote, try the setup from the '95 Maxima. Also, the beeping remote is just that - a remote that beeps when you push the buttons that confirms the remote works. I have one, and strangely enough from a '95 J30. I reprogrammed it for my '97. Remote functions are as follows:

Lock - (top large grey button) - HELD function is PANICUnlock - (Top-left button ) - Unlock drivers door (press 2x or hold for all drs)Truck - (Top-right button) - Hold for 3 seconds to unlock trunkLights - (bottom left button) - Turns on and off interior light (if in DOOR pos)

[Infinitiguy19]

You just became my favorite NICO member!!!

Thanks a lot bro you confirmed what I though, let me know if I can do ALMOST anything to repay you.

[Infinitiguy19]

Hey I hate to bring this up again and again but I have two more questions.

Can the trunk be opened with the doors closed BUT unlocked?

When the trunk is opened do you hear the door lock timer try and lock the doors?

[nosaint]

My key fob beeps and so does the car but mines probably not much help to you.

Range is about 10 feet or so, maybe a bit more if i use the skull amplifier.

i can open the trunk at any time...

[yodawill2000]

I can unlock the trunk with the doors locked or unlocked.
My 2 centavo's to this most interesting thread.

NoSaint Your car you doesn't count lol
Your Leop is a beast of a different color.

One has to wonder if your leopard came from the factory as such or was modified when still young ??

[nosaint]

car is pretty much untouched cept for wheels/stance and stereo...nothing else was touched

so alarm must be factory...cant add a beep to a remote!

[Infinitiguy19]

1993- early 1994's had the beeper sound on the remote. Nosaint's J30 is amazing because to my knowledge I have seen no Nissan President (JHG50) with as many features. The Backup beeper thing is amazing and the Nissan President came with it as a factory option.

Thank you all very much for answering my question. It seems the service manual is wrong when it says the doors must be locked and closed to open the trunk, Door switches (Closed) doors closed and unlock sensors closed (locked).

Can't imagine the "Skull Amplifier" is good in the long run for yourself.

Got to thinking, might be different if car is running or in drive. If you could see all the radio, sat, cellular waves out there....well you wouldn't be able to see!

[Infinitiguy19]

Whats that mean?

I meant cancer....

[nosaint]

shoulda paragraphed that, not sure if you can open the trunk with the car running with remote...

the cancer thing...well everything gives you cancer!

[Infinitiguy19]

Nope you can't open the trunk with the car running unless you rig a switch to normally ground the key switch (To program the remotes). and ungrounded to open the trunk with a spare remote with the car running. Hey I might actually try that.

True Hot dogs give you cancer now, Wonder what those hot dog champs feel like now.

[Infinitiguy19]

I hate to have to do this but:

Can the car phone antenna be used as a second antenna to boost the signal. Thereby increasing the distance that the key less entry would work.

[nosaint]

pretty sure its an infra red remote much like your tv...not intended to have a lot or range.
Time to step up to the after market if you want better performance

[Infinitiguy19]

Well I don't want 2 mile range and I don't want after market alarms. Sorry if I misled you but the topic is about installing a J30 alarm on a 1992-1993 Infiniti Q45. The door lock timers are 99% the same with the exception of drivers door priority. Nothing a little re-wiring can't fix.

The J30 owners manual says 49 feet so I am going to get 49 feet out of this if not more.

Sure after market alarms have more useful features but OEM keyless entry alarms are more classy.
