 Keyless Entry Failure
I have 2000 Expedition that began having trouble with the keyless entry. Since purchased as new in 2000 I have used the keypad keyless enrty. However, over the last few months this has become increasingly unreliable. First it would require that I enter my code a number of times before it worked. It then began only working on every door other than the driver door. Now it will not open any door. To make matters more concerning, the drivers door is now occasionally not opening with this keyless entry on the key fob. Any suggestion??? |
