keyless entry stoped working. If you unlock the door with the key and not open the fob works fine. of cource dealer wants to replace reciever for $500
BOTH keyless entry remotes stopped working, replaced batteries in each, same problem.
However, if unlock door with key or open door, remotes will work, but STOP working after about a minute of inactivity.
Had dealer's mechanic look at it and they determined the receiver needs replacement at a cost of $482.
I can live with this inconvenience a while longer until I can find a less expensive option. My mechanic suggested an aftermarket alarm/door lock system to replace the factory receiver.
we replaced the key remote battery and it still did not work. went to dealership and they sold us the keyless entry receiver. Part was replaced and keyless entry still does not work.
both key fob wont work unless you unlock the door with the key, then the fobs only work for a short time
also now the key is not opening the drivers door with out alot of "wiggling" of the key thought the lock was frozen the first time but has happened every time sence
Door locks do not unlock or lock. Not all doors have this problem.
Driver side front and rear door.
Chevrolet charge me $ 149.00 for diagnostic only.
