Thread: security light

so a buddy of mine bought a gtp recently, and it came with an autotap code scanner.. unfortunatley the software with it was made for windows 95 or something crazy like that, so he went online and downloaded a few newer versions and we tried to scan my car.. laptop says it cant connect we tried probably three or four times, then the car would start for a few seconds then die.. so i tried a security relearn.. this got the car running but security light blinks.. occasionally will go off but then right back on.. so last night i tried doing a security relearn again to get the light to shut off.. this time the car wont start at all.. so i did the other security relearn (out of the 2 on zzp since they were all i found) and the light went off, pulled the car in the garage and when we went to pull it out.. surprise, security light is back.. what could i have done and what the hell can i do to shut this light off?? it also feels like if i try to go WOT the car wont really let itself, and that wasnt a problem before this light

Are you using a passkey? ... has PK stamped on the key... or a valet key (no chip) inside.

as far as i know it is a passkey, it is the black key that i have always used.. (my valet key has a silver "valet" cover.. it saYS PK3 then M underneath that on the key im using.. the only one ive ever used in the car minus a time or two when i was in a huge rush

black key = prolly passkey.

***fingers crossed***

Let us know how it goes regardless.

update: it says something about a bad pass lock sensor.. how would i know if this was bad? also, what would i need to replace if i didnt want to solder something in there? the BCM or the sensor and where is the sensor located?

bump before work.. throw out any ideas you can think of on what it could be or how the hell i could fix it..

random bump

nobody else?

A lot of the cars have a problem with the harness for the pass key system that is attached to the steering column. Mine randomly started having problems with it too, I have not bought the updated harness yet Every now and then I just have to do a relearn. The harness is not cheap IIRC it was like $80-120 our cost.

what would i call the updated harness? i need to find somewhere i could purchase it
