CRS Locksmith Roanoke, VA

Transponder Key Programming

Since the late 1990s, almost all vehicles have been equipped with an engine immobilizer system. The plastic head of your key contains a tiny RFID microchip (a transponder). If the car's computer does not recognize the encrypted code on that chip, the fuel pump is disabled, and the car will not start—even if the key turns the ignition perfectly. We use advanced diagnostic tablets to connect to your car's ECU, bypass the security protocols, and sync a brand-new transponder chip to your vehicle's computer.

Smart Keys & Push-to-Start Fobs

Modern proximity fobs (push-to-start systems) are highly complex digital transmitters. We stock a massive inventory of OEM and high-quality aftermarket fobs for nearly every make and model on the road in Roanoke, VA. We can program the proximity functions, the remote keyless entry (door locks/trunk), and cut the emergency insert blade hidden inside the fob.

High-Security Laser Key Cutting

Many modern vehicles (especially Honda, Lexus, and European makes) use "laser-cut" or sidewinder keys. These keys have a distinctive winding groove milled into the center of the blade rather than cuts on the edge. They require highly calibrated, computerized milling machines to duplicate. Our mobile vans are equipped with these specialized machines, allowing us to decode your door lock and originate a perfect, factory-spec laser key from scratch.

Frequently Asked Questions

• Do I need the original key to get a replacement? No. If you have lost all your keys, we can use a specialized tool called a Lishi decoder to read the depths of the pins inside your car's door lock. We input those depths into our computerized key cutter to generate a perfect key from scratch.
• Is it cheaper than going to the dealership? Yes. Dealerships have massive overhead, and you often have to factor in the cost of towing your car to their lot. Our mobile service eliminates the tow and generally offers the key and programming at a highly competitive rate.
• What is an EEPROM service? Some vehicles (like older Lexus/Toyota models or certain European cars) will not allow new keys to be programmed via the OBD-II port if all keys are lost. We must physically remove the car's computer module, read the EEPROM microchip directly, and write the new key data into the code. We are one of the few locksmiths equipped for this advanced service.
• Can you delete the lost keys from the car's computer? Absolutely. When we program your new keys, we access the vehicle's immobilizer menu and erase all previously programmed keys. If someone finds your lost key, they will not be able to start your car.
• How long does it take to make a new car key? In most cases, we can decode the lock, cut the blade, and program the chip in 30 to 60 minutes right in your driveway.
