How to program your key fob

This vehicle's remotes can't be programmed without professional diagnostic tools — an automotive locksmith or dealer has to do it.

Order the correct replacement remote below (match the FCC ID on your current one), then have a locksmith or dealer program it. These vehicles hold up to 4 remotes, and any aftermarket alarm or remote-start must be disabled first.

Chevrolet HHR key fob battery

Your Chevrolet HHR key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.

How to replace the battery

1 Find the seam or small slot on the edge of the remote.
2 Twist a coin or small flathead in the slot to split the case open.
3 Remove the old coin cell and note the + side.
4 Fit the new battery with the + side matching, then close the case.
5 Press a button to confirm the LED lights, then test at the car.

Battery tips

Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
Try not to touch both faces of the new battery; skin oils shorten its life.
If the remote still doesn't work after a new battery, it may need re-syncing or programming.
