My remote is set to RFA 3.This morning it stopped working. When the lock or unlock button is pressed, the vehicle does not respond. The ligths do not flash, the horn does not sound and the locks do not respond. I checked the RFA sequence to verify that it was set to RFA 3 and it will work when the key is still in the ignition but once I am outside of the vehicle, it does not work.

Do you have any suggestions ?

 

This might be a stupid question, but did you check the battery in the remote??

 

first thing i would do is replace the battery in my remote. if it did not work i would then take it to the dealer.

 

I had to replace the battery in one of mine (actually I replaced both) this past summer.

 

Please try changing a battery in Hummer car remote. This usually helps. You can purchase a new or used car remote from our website - http://www.carandtruckremotes.com/index.html. We offer free shipping for batteries.

If you changed the battery and your Hummer keyless entry remote still does not work, most likely you need a new remote. You can purchase a brand new or used good condition (B-stock) remote on our website. All remotes come with a 90 day money back policy. Please click on this link to our website below

One of mine has since quit working again. Tried another new battery, but still out.

 

You might also check your remote at your local auto parts store. Most AutoZones have a simple tester that shows if your remote is actually putting out a signal.
