Default Programming Keyfobs

Hey all,

I have followed as per owners manual to the T. I can program original remote without issue. My new aftermarket one with correct FCC # worked first time but was very hit and miss and now won’t program.

I did notice once when programming mode was turned on it lock, unlocked and popped hatch as it should. Now it only cycles locks and no hatch pop. However when OEM fob is programmed the hatch never pops during entry of program mode or when key fob is married but once I test with OEM fob everything incl trunk works perfect. New fob when trying now will lock cycle like 3 seconds after holding buttons, I’ve tried keeping them held 20 seconds but no dice.

Bad fob?
Should car pop trunk when entering programming mode?

Probably bad FOB, Id purchase through AMAZON and then if it doesn't work, returns are simple.

When I programmed the one I got off Amazon, the original fob quit working. I could only get one at a time to work but never both.

Did you reprogram both at the same time? When you program a new remote, it wipes all previous matches including the original, so you have to program one then the other before exiting program mode. If not then only the one you just programmed will work - the other will have been forgotten. That's by design for situations where an original fob was lost or stolen and you don't want whoever has it to be able to access your vehicle.
