2001 Acura RL key fob battery
Your 2001 Acura RL key fob uses a CR2025 3V lithium coin cell. A fresh one typically lasts 3–5 years.
Buy Energizer CR2025 Lithium Coin Batteries (4-pack) on AmazonHow 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.
2002–2004 Acura RL key fob battery
A plain transponder (chip) key has no battery. The immobilizer chip inside is powered by the car's ignition ring whenever you turn the key, so there's nothing to replace. If your key also has lock/unlock buttons, that remote portion uses a 3V coin cell — see the remote battery steps for that.
Battery tips
- If your engine won't start but the key turns, the issue is usually a worn key or the immobilizer reading the chip — not a battery.
- A spare chip key must be cut and programmed to your car before it will start the engine.
