Auto Chip Keys& Key Services
Auto transponder and chip key duplication is the number one specialty at Interstate Security. We carry keys for most vehicles on the road today, and our team can cut and program the majority of auto chip keys the same day you walk in.
What Is a Transponder Key?
Understanding the technology inside your car key.
A transponder key is an automotive ignition key with a signal-emitting circuit built into the plastic head of the key. Each transponder contains a unique electronic serial number that communicates with your vehicle's onboard computer system every time you insert the key and turn the ignition. If the serial number transmitted by the key does not match the code stored in the car's immobilizer, the engine simply will not start.
This technology was introduced by automakers to drastically reduce vehicle theft. A standard metal key cut to the correct pattern can turn the ignition cylinder, but without the proper transponder chip programmed to that specific vehicle, the engine control unit will block the fuel and ignition systems from firing. That is why a trip to a regular hardware store for a quick key copy will not work for most vehicles manufactured after the mid-1990s.
How Chip Key Programming Works
From blank key to a fully functional duplicate, programmed to your vehicle.
Key Identification
We identify your vehicle's year, make, and model to determine the correct key blank and transponder chip type. Many newer vehicles use high-security key profiles that require specific blanks from manufacturers like Strattec.
Precision Cutting
Using professional code-cutting machines, we cut the metal blade of the new key to match your existing key or to factory specifications. Precision matters here because even a small deviation can prevent the key from turning the ignition cylinder smoothly.
Transponder Programming
The transponder chip inside the new key is programmed with the electronic serial number that matches your car's immobilizer system. Once programmed, the vehicle recognizes the new key as authorized and allows the engine to start normally.
