A modern smart key uses low-frequency RFID and rolling-code encryption to talk to your vehicle whenever you walk up to the door or press the start button. When the chip fails, the battery dies, or the fob is lost, the car simply refuses to recognize you — even if the mechanical emergency blade still opens the door.
Our mobile units carry OEM-grade proximity fobs and the diagnostic programmers required to pair them to your vehicle’s CAN-bus and immobilizer system. Everything happens in your driveway: cut the emergency blade, flash the encrypted chip, sync it to the push-start system, and test it before we leave.
Traditional metal and transponder car key duplicates cut and chipped at your home, office, or driveway in minutes.
Extra working keys for spouses, teenage drivers, or shared family vehicles — paired without erasing your original.
Backup proximity smart keys at a fraction of dealer pricing — so an all-keys-lost emergency never costs you a fortune.
