You are purchasing one fresh lithium replacement battery for your Lexus remote key. This is the battery that goes inside your remote key with the integrated blade. It does not fit the keyless entry remotes without the blade. We have those in our other listings. AmazingKeys.com sells for much less than what the dealer charges. Please make sure your old battery has the number CR1616 on it to insure a correct match. Battery manufacturer and country of origin will vary.
