The key fob buttons don't work.replaced the battery too.
The key fob buttons are lock, unlock, remote start and horn.

 

Take the contact pad off and use a pencil eraser on the board it presses on to, then clean with isopropyl alcohol.

 

Or go to EBay and order new pads

 

Mine did the same thing and the rubber pads on the back of the outside rubber piece you press had worn down. So I ordered a new key fob from Walmart for $12.36 but now sells for $10.79 online, opened it up and removed the circuit board and placed in my existing circuit board from old fob. There was a little play so put a small rubber piece between circuit board and side. Closed back up and has was perfectly for over a year now. Doing that saved me from programming the new fob.

This is assuming the battery cage is still soldered to the board. https://www.chevyhhr.net/forums/how-...ontacts-30813/

 

I was in ACE Hardware yesterday and they have all of the inserts for most key Fobs that make it like new....original replacements.

 

look at the battery holders soldering

 

Yep a lot of comments about battery clip loose or disconnected solder joints.

 

It only took a couple of times of dropping my keys to loosen up the solder joints. For a while I was re-soldering about every 6 months. I bought a new soldering iron and haven't had to solder the connections in a year and a half.

 

Me to!
