Transponder keys are more advanced vehicle keys that prevent theft. The market first saw this type of key in the 1990s. It was a response from General Motors, who in 1985 had developed the Vehicle Anti Theft System to reduce Corvette thefts.
To deter car theft, there are now more transponder key variations. Several automobiles use the traditional transponder keys as they work perfectly.
How do they work exactly?
The Key Takeaways
- A Transponder Key, commonly used in cars, embeds microchips that transmit signals to the car, starting the vehicle when the signals match.
- The hardware stores are not able to duplicate the transponder keys.
- Keypad Locksmith is a specialist in enhancing security systems in homes and automobiles. Contact us today regarding your dilemma regarding your transponder keys.
What Is a Transponder Car Key?
Transponder keys use microchips to transmit a signal that a receiver can read remotely. The manufacturer programs the microchip with a unique serial code.
When you place the key in the ignition, the chip emits a unique code signal. The onboard computer of the car then checks this code and allows the engine to begin if the code matches the one stored in the system.
Most cars made in the last 20 years use transponder keys as part of their anti-theft security. Keyless entry systems operate garage doors, gates, and homes.
How Does a Transponder Key Work?
A microchip embedded in the head of the transponder key controls it. The car’s computer transmits a radio message to the transponder when the key is inserted in the ignition.
The receiver of RFID (radio-frequency identification) must be able to detect the correct serial numbers to unlock or open. Transponder keys, which are similar to fobs and car locks, are used to unlock garage doors, gates, and other home security systems.
This type of key provides an extra layer of security to cars and other devices by preventing any key that doesn’t contain the code from being able to access a unit.
Why Are Transponder Keys More Secure?
In two ways, transponder keys increase the level of vehicle security. By making ‘hot wiring,’ or breaking the car ignition lock ineffective, they help prevent and deter car theft.
- A more complex mechanism. The car will not start if it cannot detect the microchip of the key or its exact serial number. The digital ID of a transponder is almost unique, whereas a standard ignition key has only a few standard combinations.
- Digital System. Digital identity allows for many more combinations than standard mechanical keys and reduces the possibility that another person’s key will be used to unlock your vehicle.
- Prevents Hot-Wiring. This mechanism prevents the process of hot wiring a vehicle.
Transponder keys are not foolproof. Even with the security of transponder keys, criminals have found ways to get into cars.
Where Can I Find a Replacement Transponder Key?
If you are unable to replace your transponder key, contact the dealership where you purchased your car. In the event that this does not work, you can try these steps to replace a transponder:
- A reputable automotive locksmith with experience in transponder keys can be contacted. Many times, they can replace or program a key at a lower cost than the dealership.
- Give the locksmith your vehicle’s model, year, and make.
- It can be easier for them to make a new key if you have an old, non-working one. Many locksmiths provide mobile service and will come to you on-site to create a key.
Transponder keys can be programmed and replaced in less than an hour. Not all hardware or locksmith stores have the necessary equipment to replace transponder keys.

What Is the Cost to Replace a Transponder Key? Why Is It So Expensive?
The cost of replacing a transponder can range from $50 to $200 depending on its complexity.
Locksmiths are asked this question about transponder keys the most. The cost of rekeying a key that has a microchip is significantly higher than a traditional key. dealers charge much higher prices for new transponder keys than car owners are expecting.
There are several factors that contribute to the high cost of a transponder. One of the reasons they are expensive is that they require special equipment.
The microchips in the heads of keys are very expensive to buy, even for locksmiths and dealerships. The traditional key of the vehicle device is easily and cheaply copied. You may still be able to open doors and roll down windows without the microchip. The car engine will not start when the key is turned in the ignition.
How Do I Program a Transponder Key Myself?
It is not possible to program the key without special equipment or skills. Your local locksmith should also be able to help, as well as the car dealership.
Transponder keys can be replaced by contacting your local locksmith, Keypad Locksmith.
Transponder Keys Have Made It Impossible to Lock Your Keys in the Car
The feeling of panic that occurs when you discover that you accidentally locked your keys in your car is well-known. Often, it happens when you are on vacation, in a hurry, or on your way to an important meeting. With transponder key technology and increased security in cars, it may be difficult to open your car yourself.
What to Do if You Lock Your Keys in the Car
Here are some ways to try and unlock your car if you’re standing outside with your keys inside.
- You may be able to use a straightened hanger to unlock your car if it has electronic buttons at the edge of the windows. Create a small hook at one end of the hanger. Insert the hanger between the rubber and glass on the upper side of the frame. Insert the wire slowly into the car while bending it. Aim for the electronic lock button.
- Some cars allow drivers to access the trunk of the vehicle by moving the rear seat. You can unlock your vehicle by opening your trunk if you are able to do so.
- A locksmith will be needed to help with vehicles that have locks built into the interior of the door handle.
Emergency Situations
Most local police officers are not able to respond in non-emergency situations to calls for car lockouts, and many don’t wish to damage vehicles. If you call in an emergency, the police and locksmiths are more likely to respond.
In the event of an emergency, you can break the car window to free a trapped child, animal, or person. Temperatures can reach dangerous levels in just one hour.
How to Prevent Another Lockout
Consider taking these preventive measures if you are prone to locking yourself out of your vehicle.
- Do not lock your car using the door handles. After exiting the vehicle, lock it from the outside.
- Use a magnetic lockbox to hide an extra key somewhere on the exterior of your vehicle. Place it in a hidden area to avoid car burglaries.
- Many new models have electronic locks that are easy to use and can prevent you from locking keys in the car. Upgrade to a transponder or car with a keyboard. Or, consider a proximity device that allows keyless entry. This technology ensures that you will never lock your keys in your car again.
- Do not let your kids play in the car. You may end up locked out if your children are still inside.
If you’ve ever been locked out of your car, it can be embarrassing and frustrating. Taking simple precautions will reduce the likelihood that you’ll need to call a locksmith in an emergency.
