Remote Starter Won't work after new key programming

[zcap]

Hi Everyone.

I had a remote car starter installed in my 2005 Nissan Quest when I bought it new. Now few years later, I lost one of the keys and went to a dealer to get a new one. Didn't tell him about a remote starter. Dealer made a new key, but now the starter stopped working. Every time I use it, it cranks the motor, then gives up, throws up a system code about security key mismatch.

I know my starter is prestige. I can see the control box under the panel, it says Part Number 136-4292. And my remote says "Prestige aps0e3b4s". It is so old I can't find any info about how it can be wired.

Any ideas on what could be wrong? I understand there is a piece called bypass module that deals with a security chip in the key. Does that need to be reprogrammed somehow, now that I have new keys?

Any help is appreciated, I'd hate to go back to the dealer.
