Laser Cut Keys are another innovative, theft-reducing advancement in automotive technology. Pioneered by BMW, Mercedes, and Volvo in the 1990s, Laser Cut Keys need to be programmed with the car and, like other programmable automotive security technologies, require an exact match between key and car. When the key does not exactly match, the engine is disabled.
Laser Cut Keys require trained, knowledgeable and, above all, competent locksmiths. Incorrectly made, a Laser Cut Key will fail, at the very least, fail to start the engine. At worst, a badly made key could result in ignition problems that would be difficult and expensive to repair.
