Lost/stolen Key Fob.....What now???

[BarbaraD]

My daughter left her purse unattended 2 nights ago and it got stolen. The only valuable item inside was her Versa intelligent key fob, the oval kind with the manual key inside. I've been reading lots of information online and am a little confused. I plan to get a new key fob of the same type, which I know I can buy online at keylessride.com for $124. So that would give me a replacement of what was stolen. I've also read instructions on how to program the fob (slip the manual key in and out of the ignition 6 times, etc......). But there are some things I'm not clear on.
First, let's suppose a "bad guy" took the purse, saw my daughter's drivers license and knows where we live, and decided to drive over here and steal the car in the middle of the night. As a temporary measure, we've blocked the Versa in the driveway with another car, so there's no way for a thief to drive it away even if he gains entrance to the car.
Now assume I decide not to replace the stolen key fob immediately, and just get by on one. (When I bought the vehicle new, I was given two and I still have one.) If I get inside the vehicle with my key fob and went through the programming steps I've mentioned above, then I assume that my key fob and the manual key are now coded differently than the fob and manual key the thief has. YES? OR NO? Would he still be able to come over here and use the manual key to get in the car and drive it away in the night after I've reprogrammed my own fob and key and am happily assuming the car is safe?
Since I'd like to give someone a chance to mail me the purse/keys/drivers license, I would like to delay doing anything for a couple weeks. If I don't get the keys back, well, that's what I expect, and I would then go ahead and purchase a second key fob with the manual key inside, just like my original. So now, let's say this has come to pass and I'm sitting here with my original key fob/ manual key reprogrammed. Can I now take both sets of key fobs and do another reprogramming? That is to say, is there any limit on the number of times the car will perform the reprogramming? I would think not, but I can't find any info on this. I sure would like to know the best way to handle this dilemma.

give me 24 hours on this. I'll ask at work tomorrow to see what the best thing to do is.

So glad you found my question, Promise Land. I was hoping you would. Thanks.

uh, oh. If you know to look for me, my cover is blown!

The control module will accept a third keyfob if you decide to replace the stolen one. But, it will still accept the stolen one too. The only way to prevent the stolen one from working would be to have the dealer change the body control module for a different one, and then reprogram that new one to recognize your current fob and any new fobs you add to it.

Yeah, your cover's blown! Actually, I did lots of reading on this site and found that the wisest and most thoughtful, informed answers were written by you.
Here is what I understand to be the situation with my problem:
The Versa has something called a "Control Module", that is programmed in the factory to a certain code. Let's call it Code 1. When you buy the car new from a dealer, you also receive two key fobs set to Code 1. An owner can later buy additional key fobs and program them himself to Code 1 by going through the process mentioned in my original post. (By the way, the instructions are available here: http://www.programyourremote.com/classi ... sp?cid=257)
This DIY procedure is all you need to do anytime you just need to have more fey fobs programmed to your Versa. Keep in mind, you are NOT getting a NEW code on your key fob. It's going to be Code 1. Therefore, I can't just go out into my car and reprogram my remaining original key fob and think "Ha ha, Mr. Thief, now you are powerless to steal my car, because I just had my Control Module and my key fob set to Code 2!" The Control Module is going to send Code 1into my key fob. Nothing can change the code in the Control Module except the dealer's service department. So if you just want more people in your household to have their own key fob, you don't need reprogramming of the Control Module. But me, I've got a potential thief out there with the second key fob to my car, and I have no choice but to take the car to the dealer and get the Control Module reprogrammed to a new code, Code 2. Later, if by chance the lost/stolen key fob is returned to me, all I would have to do is DIY-reprogram it myself to Code 2.
If I've got it correct now, Promised Land, please tell me so. Thanks!

LOL!

He is definitely the best person to ask with a question ... he always seems to find the answers

[Promise Land]

BarbaraD, that 's exactly it. Though I can't remember if the "Code 1" can be changed by the dealer or they will have to install a new module. Either way it stinks.

Actually, what I said above isn't correct at all. I was talking about it yesterday to a locksmith, and found out something completely different. The control module doesn't have a Code 1 or Code 2. It's the keys that have the codes, and the control module is programmed to recognize/accept the keys.The control module can recognize up to 5 keys. Let's call them A, B, C, D, and E. The control module in my car is programmed to recognize A and B right now. The locksmith or the dealer will use a tool called a "scan tool" to erase the memory of all keys. At that point, key A and B will still open the vehicle locks manually, but will be unable to start the car. The locksmith said he does not recommend changing the locks on the car because it's too costly and if you just watch what you keep in your car you should be ok.
I still have key A and will buy a new key, key C. Key B is the one that got lost and maybe stolen. I will need the control module programmed to recognize Key A and Key C. So I have a "reprogramming" or "registration" done by the locksmith or dealer, and then Key A and Key C will be able to start the car. Since Key B is not present, it is not going to be reprogrammed and even if it is found someday, it won't be able to start the car. I could go through a second reprogramming at that time though for all three keys. You have to start over each time. I may still have this wrong, but I swear there's just no information about how this really works. Perhaps in the future, some will read this thread who can write it up accurately. This is the best I can do for now.

You pretty much have it right. Since your car has the optional intelligent key system, only the dealer can reprogram the car using their CONSULT III diagnostic computer system. To do so, the dealer would need all i-keys to be present at the SAME time. This step essentially "un-pairs" the missing i-key from the car. The only issue is that the mechanical key can still access the car unless the mechanical lock(s) are replaced.

A few notes: 1)Most lock smiths do not normally have a CONSULT III laying around (costs roughly $5-6K) so it will most likely mean a trip to a nissan/infiniti dealer. Call around for the best price to do the job. 2)When buying i-keys online, be sure to buy from a reputable source. There was a recall for ikeys a few years back and I have heard a few of those being sold online.
