Remote / key fob programming

You can program Toyota remotes yourself with a sequence of door and ignition movements. Have every remote with you. Try the main procedure first; if the locks don't cycle, use the alternate.

Key programming

This key fob can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new fob, so a replacement has to be set up by an automotive locksmith or a dealer.

Order the correct replacement fob below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.

Toyota Solara key fob battery

Your Toyota Solara 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.
