Transponder Keys vs. Remote-Controlled Keys: What’s the Difference?
Transponder keys and remote keys have been around for decades now, yet a lot of people still confuse one with the other or believe they’re the same.
To help you understand the difference between them, we’ll shed light on both types and provide helpful tips on what to do if you encounter problems with them.
What are transponder keys?
A transponder, as its name suggests, is a combination of a transmitter and responder. You can find this system in many modern cars with slight variations in their operation.
The main purpose, however, is similar in all cars: the engine can’t start and the car alarm system can’t be disarmed without the transponder.
As you can imagine, this presents a problem for car thieves.
What are remote-controlled keys?
Remote keys can still start your car, and they can be used in locking/unlocking your car, too.
The technology works by sending a weak signal to your car. If it’s recognised, your car opens or locks. We mention ‘recognise’ because this signal is unique to your key and works only with your specific car.
Which is better?
There are four criteria that both types of keys should be evaluated to help you understand which is better: servicing, convenience, and security.
The technology used in transponder key programming is truly innovational. But remote car keys are just about as useful, if not more.
Remote keys allow some control over your car from a distance, and even from inside your pocket or purse. Transponders have a passive function and offer more security than convenience.
Finding a locksmith who can service a remote car key is somewhat easier than finding a locksmith who knows transponder key programming.
Dealing with broken transponders requires the right training and tools, both of which regular locksmiths don’t possess. Also, because transponders are more expensive than remote keys, the cost of servicing tends to be higher, too.
You also have the option of requesting your car dealership to fix or replace your remote or transponder key, but they’ll charge a premium price. Working with a certified locksmith is easier on the wallet.
A transponder key plays a significant role in your car’s anti-theft system. In fact, the reason why they were made was to stop cars from being hot-wired and stolen. But what about remote car keys?
If you compare the level of encryption for both types, transponder keys win hands down. That’s because, while remote car keys enhance vehicle security, the focus of the product is convenience.
