Transponder keys contain an electronic transmitter and must be programmed to work with a vehicle’s recognition system.
When are Transponder Key Services Needed?
- You are attempting to have a new key recognized by the vehicle.
- An additional transponder key is to be added to the vehicle.
- You have lost the only key to the vehicle.
- The key turns the ignition but the vehicle does not recognize the key.
- A new key fob or replacement key is to be added to the vehicle.
What Is A Transponder Key?
A transponder key contains an embedded microchip. The microchip communicates with the vehicle to verify and validate the key. Traditionally, a transponder key will also contain a mechanical key bit to physically open the vehicle. Some transponder keys may also contain other additional features such as a remote keyless entry.
Transponder Key Replacement vs. Programming
Key Replacement provides a new physical or electronic key. Programming a transponder key enables the vehicle to recognize a supported transponder key.
You may need transponder programming when adding a supported key that the vehicle does not yet recognize. You may need replacement when the existing key is lost, damaged or unusable. If you also need remote-button functions, we will confirm whether the replacement key or fob requires separate programming.
Chip Key vs. Key Fob: What is the Difference?
A key with a transponder chip is used to give a vehicle recognition function. A key fob or a remote provides functions such as remote opening or closing of a vehicle and other supported function.
Tell us exactly what happens when you use the key, including whether it opens the door, turns in the ignition, starts the vehicle or operates remote functions.
Can a Locksmith Program a Transponder Key?
Programming a transponder key is possible if locksmiths support the key and the vehicle. Key type, year, make, model and current key are all factors in determining if locksmiths support programming a transponder key.
Programming every vehicle is not possible; dealership service is still required.
Can a Transponder Key Be Programmed Without the Original?
Sometimes, the original key is not necessary. In some systems, losing all keys is a more complicated situation than adding a spare.
The vehicle and the owner authorization are necessary to perform the service.
What if the Vehicle Does Not Recognize the Key?
There could be several causes for a recognition issue, such as the transponder key, the key’s compatibility with the immobilizer, key programming, or the vehicle’s security system. The most effective way to resolve this is to analyze the vehicle in question, the type of key, and the behavior of the key and/or immobilizer. Repeatedly attempting unverified programming options is not the best use of the time.

Transponder Keys FAQs
What is a Transponder Key?
A transponder key contains a chip that communicates with the vehicle’s immobilizer or recognition system. The remote-button functions may be built into the same key or provided by a separate fob.
Why won’t my key open and start my vehicle?
A key may have both a mechanical blade and a transponder chip. If the vehicle does not recognize the chip, the key may open the door but fail to start the engine.
Is there a difference between a transponder key and a key fob?
A transponder chip helps the vehicle recognize an authorized key. A key fob commonly controls remote functions such as locking, unlocking or opening a supported liftgate, although both functions may be combined in one device.
What is the cost for programming a transponder key?
The cost depends on the vehicle, the type of key, and if the key must be replaced as well.
Is transponder key service available in Tarzana?
Yes. We provide transponder key service for supported vehicles in Tarzana. See our Tarzana service-area page for local coverage details.
Are Transponder Keys Programmed or Replaced?
The year, make, and model of the vehicle must be given, as well as the location. The situation with the current key must be given as well, and if a working key is available. Lock & Key Pros will let you know if the service you need is to have a transponder key programmed, replaced, a car key replaced, or a key fob programmed.
