I have a 2005 sts and just yesterday this started. If I click the unlock button on the chirper it unlocks all the doors but the drivers door. The only way to unlock it is if I use the key or unlock it from the inside. Any ideas?
IceDigger, Common problem with the door. Same thing happen to my 06 STS. I replaced the driver micro switch. Located inside the door. Most dealers will want to replace every thing in the door. That how they stay afloat. Call rippy's auto parts. Danny
You'll need the OEM radio to change the memory seat, remote start, & security settings. Some members wire it into the system from the trunk. I think there are also some aftermarket solutions. Do your research.
19120306 is the part # for the drivers door it's called the k housing. Also for a temporary fix until your new k housing gets replaced you can spray electrical contact cleaner through the door handle with an aerosol can with a straw attached to it the contacts that get corroded are on inside the handle. Pull out on the handle and spray downward. I used brake cleaner (not the best idea but it was just temporary until my new k housing came in)
