How to replace your keyless remote battery

[Qxxx4]

all you need is a small flathead screwdriver and the replacement battery a 3V CR2025 you can get this for a few bucks at radioshack

pry this part starting here, then follow along all around little by little until the entire piece pops outtheres your battery NOTE its upside down here, i wanted to show the part # MAKE SURE you put it in with + side facing down (opposite of what is shown)dont worry about it resetting or anything, i had the battery disconnected for a good 5 minutes as i cleaned the crevacesthis is pretty straightforward and a no brainer but im sure it will be useful to someone or maybe somebodys wondering what the inside of the remote looks like

Pretty isn't it? Now, Mr. Electronic, can you suggest what to do for a remote that doesn't function, regardless of battery replacement?

Easy, install a remote start/alarm system and now you have a new keyless entry remote!

AJRK, there is a method to "reset" your nissan remote, and pair it with the car..... ive done it before, cant remember the instructions but it can be found by searching

[fueler]

the following is for the 01+ (the procedure for my 99 qx4 had a few extra steps not mentioned here)

Get in the vehicle. Close and lock all doors utilizing the driver's power-door lock/unlock switch. Insert and remove the ignition key more than six times within a 10-second period (at a rate of one insertion/removal cycle per second). Don't rush the process, and be sure the key is completely withdrawn from the ignition-key cylinder each time it's removed. Turn the ignition to the ACC position and press any button on the remote one time. The hazard lights should flash twice, letting you know your mission is a success. If you were going to program more than one remote, you'd simply unlock and lock the doors once again with the driver's switch and press the one button, one time, on the second remote. The procedure is completed by turning the ignition off, unlocking with the driver's switch, and opening the driver's door.

Thanks Fueler! I'll be doing that as soon as I get back up there. I just can't figure out why the remote would have lost its programming.

theres a lot of reasons why your keyless might not be working.... this procedure just happens to be free so it worth a try

if that doesnt work, the next thing i would try is programming a brand new remote....
