How to program your key fob

This remote 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 remote, so a replacement has to be set up by an automotive locksmith or a dealer.

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

Find your key type below, then match the FCC ID printed on the back of your existing fob — or, for a plain transponder key, the blank code — to be sure of the right part.

Acura RDX key fob battery

Your Acura RDX key fob uses a CR1616 3V lithium coin cell. A fresh one typically lasts 3–5 years.

Buy Panasonic CR1616 Lithium Coin Batteries (4-pack) on Amazon

How to replace the battery

1 Look for a small notch or screw on the side of the fob where the key blade meets the buttons.
2 Pry the housing apart with a coin or small flathead (or remove the screw).
3 Pop out the old coin cell, noting its orientation.
4 Insert the new battery the same way up, then snap the case shut.
5 Test the buttons — if they work, you're done.

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 buttons still don't respond after a new battery, the remote may need re-syncing or programming.
