Modern vehicles rely on transponder keys containing a signal-emitting circuit with an electronic serial number. If the number doesn't match your car's computer, the engine won't start. That's why you need specialists who understand the technology.
We carry key blanks for most domestic and foreign vehicles and have the advanced programming equipment to duplicate and program transponder keys on-site. Most auto chip keys are cut and programmed the same day you walk in.
