Battery Replacement

It is possible to replace the battery if your key fob won't lock or start your Lexus. It's a relatively straightforward procedure, and can be accomplished at home or at a dealership. It is recommended that you read the owner's manual before starting. The exact steps may vary between models and years.

First, make sure your hands are dry and clean. Injecting moisture into the fob can damage or rust your brand new battery. Press the release button on the side of the key fob to unlock it, then remove the key blade that is mechanical (if there is one). Use a screwdriver or other flat tool to pry off the cover plate and expose the battery. Remove the old CR1632 and replace it with a new one. Make sure its positive side is facing up. Then snap the fob back together and you're ready to go!

This kind of battery is available at most hardware stores or auto parts shops and even some locksmiths. Prices vary based on the retailer and the region.
