Keyless remote locks - no unlock
 

Hey guys,

I have a 97 Blazer. The remote will lock, but not unlock. I have tried 2 different remotes and same thing happens. None of the doors including back rear gate/window will unlock at all when the unlock button is pressed.

Has anyone heard of this? How can the lock button work, but the unlock button doesn't???

Thanks in advance!

p.s. I tried doing the unlock/on/off/on/off combo directions for reprogramming but the locks never cycle. I also tried holding down the lock and unlock for 7+ seconds.

Its weak but the first thing I would try is changing the battery and/or look for corrosion on the pcb. Perhaps taking the battery out for a while will reset something in the key fob.

Hey thanks. I will try it, but I believe I already tried both of my fobs. I can't understand how it will lock but not unlock.
