Fix for Cobalt Remote Key If Only Some Buttons Are Not Working

The buttons in Cobalt (and some other GM vehicles) key fobs are prone to wear in such a way that some buttons may work and some do not. An easy and very inexpensive fix for this is to replace the case (buttons included), retaining the electronics module inside. GM never told us about this did they ?

I do this all the time for friends I always keep a box full of shells and buttons.

An other way if the buttons aren't availlable is to punch out a piece of airduct tape and apply it to the worn out button pad. It already has glue on it.

These are just shells, but I might have one hanging around. Do you want one with or without remote start?

Auto start is the weakess signal on the KeyFOB. Plus it won't work if you have difficulty with your lock button if it's wore out. Battery under 3Volts I replace. The red button is the strongest signal at almost 3 times the power of lock, un-lock and trunk lid.

Bronx,

Any auto parts store should have em. I just replaced mine for $4.00. I believe the battery size is CR2032.

Hijack: Does anyone know a way to reprogram them since mine is toast? Bought the car used Friday and noticed the key fob didnt work. Figured it was just a battery and no big deal. Opened it up to replace the battery at the parts store. Boom, the batter holder has broken off. Figured I could solder it on. Nope, not happening. So, I plan on ordering one from ebay. Do you nkow of a way to program them without taking it t the dealership?

This was found in the manual, also the battery i needed

Quote:
Programming Transmitters to the
Vehicle


Only RKE transmitters programmed to the vehicle will
work. If a transmitter is lost or stolen, a replacement
can be purchased and programmed through your
dealer/retailer. When the replacement transmitter is
programmed to the vehicle, all remaining transmitters
must also be programmed. Any lost or stolen
transmitters no longer work once the new transmitter
is programmed. Each vehicle can have up to four
transmitters programmed to it.
