Just went on a road trip for 13 hours and ran the a/c the whole trip, now upon arriving at our vacation destination, I discovered that my keyless entry door code no longer works. The only thing I can remember is during the road trip, the a/c unit under the passenger kickboard dripped a little(I thought condensation). Could the exessive a/c usage cause my key pad to stop working? Thank you in advance for your help. Man, my '05 Expy has given me a fair share of problems ;(

 

Did you figure out your issue?

I am having the same problem....keyless entry on door does not respond nor can I program my keyless remote Fobs turning the ignition from 3 to 4 position eight times...seems like a fuse, but nothing blown that I can find nor do fuse listings appear to be related.

By the way, keyless entry on door is wired version, not wireless that needs a battery.

 

Try pushing the buttons real, real hard and see if it works. Sometimes the contacts become corroded under the buttons, making contact difficult.

 

Tried that again...neither Keyless remote (key FOB) nor keyless door entry (door keypad) responds, so can't be programmed. Figured are related and uncommon as haven't seen the two frequently at issue at the same time....

I have checked the fuses in general in the cab and underhood, but is there a specific location/designation?

 

I tried the the same fuse checks, but all check ok. Haven't tried programming a fob. All my fobs work. The entry code backlights so it's getting power. I even tried the factory code, but that still didn't work.

 

Did u ever resolve this and if so how?
