Wireless transponder keys were developed primarily as a theft deterrent. In addition to the physical key, a computer chip inside the fob exchanges a series of random-looking codes with the vehicle’s onboard computer. If the codes don’t match an “immobilizer” prevents the car from starting even if the key fits.
In addition to key cutting, we have the latest equipment for mobile transponder key programming so we can take care of everything right on the spot. That includes locking old transponder key codes out of the system so that lost or stolen keys no longer work.
