What used to be an intermittent problem has turned into a consistent problem. None of my key fobs seem to work any more. I can't unlock, lock the car, remote start etc. I have a 2012 chevy cruze ltz with the push to start and keyless entry. The key is recognize if I insert into the slot in the console but none of the fobs functionality seem to work. I have replaced the batteries for both remotes and nothing. Any ideas, I really do not want to have to go back to the dealer again...

How is your Tire Pressure Monitoring System working? Anything you've added in the mirror area? (Like a dashcam?)

I dont know what the inside of the keyfobs look like, but the ones in the 90's/00's used a carbon fiber pressure point to "complete the circuit" on the keyfob board when pressing a button. Over time the 'carbon' wears off and the circuit cant be completed, hence no action when a button is pressed.

there are 2 ways to fix this particular problem:

On my 2005 Grand Prix I took the easy route by glueing alumium foil dots on the rubber carbon points. The AF will give the same result as the carbon. Positives of this fix is its easy and simple to do. I used a simple hole punch to create the patch and super glue to connect it. Drawbacks - the dots tended to come off after 6-9 months requiring re-glue. Sometimes when the dots came off they 'cross circuted' the keyfob which gave crazy results like the trunk opening along with the doors.

You can buy liquid carbon (I forgot eaxctly what this is called) and paint the button bottom. This works longer term.

Hope one of these helps you.

It doesn't look like its the key fobs, I almost sure it is the receiver. Can I just replace the existing receiver in the car with a new one or would I have to reprogram it?

Stop at a dealer with both of your key fobs.....all dealers are supposed to have a fob tester.

The tester is nothing more than a receiver.......they place your fob on it and press each button.......the receiver will emit a tone with each button push on a good fob......most dealers do this as a no charge.

Good luck,
Rob

Same as the TPMS receiver, and you said it's working fine.

I'd suggest following Robbie's advice and having the fobs checked.

Darn, I though there was a thread here not too long about about someone who had a intermittent problem and then it cleared up - but my googlefu isn't turning up anything.

Is it the thread I linked to earlier?

Okay, I solved the issue. Apparently the new batteries I bought were bad. Not sure of the probability of getting two bad batteries in a package though, thanks for suggesting to get the key fobs tested.
