I'd have to agree. If you get the remote open (as if you were going to
change the battery) then you should be able to see the model and possibly
even the maker of the IC inside.
I was able to find a data sheet for the IC used in my 2003 S-10's key
fobs...in that case there was no description about how do any needed
"programming" to the IC. Nor is there anything on the circuit board to which
a programmer might connect. Maybe it's done via the onboard radio
It doesn't matter very much to me any longer. One remote went bonkers and
the other has gone missing. I don't care to get them replaced.
Here is an example of a keyless remote site, offering both aftermarket and
fobs and programming assistance. I dont believe this is the site I
originally found, but
it illustrates the claims anyway.
I was able to buy a new remote for my 2000 S-10 and program it myself.
I now have a 2006 Grand Prix and it must be taken to a dealer to be
programmed using a scan tool. The programming changes from vehicle to
vehicle, but the fact still remains, the manufacturer is making it
harder for the DIY to DIY...
AutoZone was no help for me.
I reprogrammed my 98 GMC Jimmy the same way shiden_kai said.
1.. Close all the vehicle doors.
2.. Insert the ignition key into the ignition lock cylinder.
3.. Press and hold the door unlock switch.
4.. While holding the door lock switch in the unlock position, cycle the
ignition ON, OFF, ON, OFF.
5.. Release the door unlock switch. The doors will lock and unlock to
confirm the program mode.
6.. Press and hold the LOCK button and the UNLOCK button simultaneously on
one transmitter. After a delay of approximately 15 seconds, the doors will
lock and unlock to confirm the programming of that transmitter.
7.. Repeat the previous step to program up to 4 transmitters.
8.. Turn the ignition switch to the RUN position in order to exit the
keyless entry transmitter programming mode.
9.. Operate the transmitter functions in order to verify correct system
