Brand New BMW Transponder Key

Have you lost your car keys? Would you like to have a spare for emergencies? We�ve got you covered! This is a brand new uncut transponder key blade, that is compatible with 2006-2009 BMW Z4 and 2001-2003 BMW Z8 models. A transponder key blade adds an extra level of security over a traditional car key. It has a small transponder chip embedded in the key that once it�s inserted into the ignition, a unique signal goes to the vehicle�s Engine Control Unit (ECU), activating the engine. This has a high security key blade. A high security key protects against fraudulent ignition tampering. The key will require a specialized laser cutting machine for origination and programming. If the ECU doesn�t recognize the unique code of the transponder, the immobilizer will activate and the engine will not turn on, helping to deter unlawful entry and theft.
