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
Used the remote last winter. Now this year it will not work at all. Remote door locks and alarm still work fine.
The FOB will work only it I am within 6-8 feet.........fob battery replaced......still an issue
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.
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.
