Transponder - a technology that prevents car theft

Have you ever heard of the term "chip key"? A transponder key is exactly that — a car key equipped with an electronic authorization device called a transponder. We use it to start our cars, newer motorcycles, and other types of vehicles.

But why do we need this fancy technology? So back in the early 90s, car theft was a significant issue. To combat it, car manufacturers stepped up their game and introduced high-security car key systems (also known as laser cut keys) and transponder technology.

So what's the deal with the transponder? This device stores a unique "password" for your vehicle. This helps ensure that only the rightful owner can start the car — Adding an extra layer of protection against theft. Pretty cool, right?

Now that we've got the basics down, let's dive into how this key actually works.

How does a transponder car key work?

When you insert your key and turn the ignition, the antenna which is an induction coil located around your vehicle's ignition, powers up the transponder inside your car key, allowing it to transmit a radio frequency signal containing a secret "password" to the anti-theft system of the vehicle — If the password matches, voila, your engine starts!

But what if you lose your key or need a spare? Duplicating a transponder key isn't as simple as copying a regular old mechanical car key. It requires specialized programming procedures, and a special car key programmer needs to be connected to your car to extract the correct password and match it with a new transponder.

It's worth noting that transponders are not one-size-fits-all. Each car manufacturer develops its own anti theft system, meaning there are no universal OEM transponder chips. Plus, transponders come in a variety of casings, such as ceramic or glass, and can have different looks. So, next time you start your car, you'll know that there's a lot more going on behind the scenes than just turning a key!

In short, a transponder key is an automotive key that contains a microchip that can store and send data. Car manufacturers use it to store a unique "password" for the vehicle. It sends this "password" every time the ignition cylinder is turned on.

Interesting facts about transponder keys

  • Currently, there are more than 30 different types of transponder systems available.
  • Transponder technology decreased national car thefts by more than 40%.
  • Today, 100% of car manufacturers use transponder technology.

Can I start my car without a transponder key?

No, If your immobilizer system is activated, you will need a programmed chip to start your vehicle. Luckily, an authorized dealership or an auto locksmith can program new transponder chips to your car if there are any issues.

Can I bypass my transponder key?

Yes, disabling your car's immobilizer system is possible, but we advise against it. The main purpose of the immobilizer system is to immobilize your vehicle in case of a theft attempt.  Disabling it will make your car vulnerable.

The Importance of Transponder Key Technology in Car Security

How does transponder key technology prevent car theft?


car-theft-via-door-force

In the past, stealing cars was a big problem because they lacked anti-theft features. This made it easy for auto thieves to come up with clever ways to steal cars. One popular method was forcing the ignition switch to the "on" position using a flat screwdriver — Another method was hot-wiring the vehicle and bypassing the ignition system altogether. Car companies rushed for solutions: transponder technology was one of them.

Transponder keys have revolutionized car security. What is unique about these car keys is that they can store data and transmit it when powered — To start a vehicle equipped with transponder keys the correct "password" must be sent. It means that if someone tries to force or bypass the ignition switch without sending the proper signal to the anti-theft system, the car will simply not start.

The unique abilities of transponder keys have made car theft much more difficult. Thieves can no longer use the old methods. With transponder technology, stealing a car requires much more effort and skill. This technology has made car theft significantly less common than it used to be.

So next time you start your car with your transponder key, remember that you're benefiting from a technology that has significantly reduced auto theft rates and gives car owners greater peace of mind.

Statistics do not lie — Car theft has declined dramatically since the introduction of transponders keys. See the graph below:

Many vehicle manufacturers started implementing transponder keys in their cars as early as the late 1990s. In fact, some Honda car models were already equipped with transponder keys as early as 1998, like the Accord model for example. Initially, these keys were only put on higher-end and luxury vehicles, leaving cheaper cars without this advanced security feature.

Not all car brands had an easy time implementing this technology. For example, Ford struggled with certain models, such as the F-250 and F-350 trucks which weren't equipped with transponder keys until 2008! Today these models are amongst the most stolen cars in Canada according to statistics, which means that they carry a higher theft risk than other vehicles. This is something that prospective truck buyers should keep in mind.

Wondering if your car key is a transponder key? It's worth noting that according to Canadian automotive import regulations, all vehicles from 2008 and up must be equipped with chip keys. So if you own a 2009 or newer vehicle in Canada, it almost certainly has transponder keys.

For older vehicles it's actually quite easy to find out. Most vehicles that use transponder key technology have a security light indicator. If your car has a security light, it is likely equipped with transponder keys. You can find the security light on your dashboard, center console, or near the windshield inside your car.

There is no universal code or standard on how a security light should appear, so vehicle manufacturers design their security light indicators based on their preferences. Security light indicators could be an icon of a lock or a key, a red word "security," or just a tiny red light. See below the different types of security lights:

If you are unsure, you can always phone your local dealership or an auto locksmith for advice. They will be able to tell you whether your car is equipped with a Transponder key system based on their database.

*Please note that all newer vehicles equipped with a push-to-start system have a transponder chip inside the car key.

All the different types of Car keys

A look at the different transponder key types and how they work


A standard transponder key is just a car key with a chip inside it. Over time, transponder keys have become more complex. Automakers started rolling out new types, and today there are many options for transponder keys — let's take a look at all of them.

1.2.3.Regular Transponder Key / Laser Cut Car Key / Tibbe Keys

A regular transponder key looks like a typical metal key with a plastic top (as depicted in the picture). The transponder itself is housed inside this plastic casing. It's worth noting that this type of key can come in three different cutting styles: a regular standard cut like in the picture, a laser cut (also called a "sidewinder" cut), and a tibbe key which is typically used in Jaguars and some Ford models. Regardless of the cut, all keys will still have the plastic top and transponder inside.

remote-head-key

4.5.Remote Head Key / Remote Flip Key

A remote head key, also known as a "car remote" or a "key fob." It is a type of transponder key and consists of two parts: a transponder and a remote. The remote flip key is almost the same as a remote head key. The main difference is that the blade on a remote flip key is stored inside the key. When you need to use the key, press the button on top of the key and the blade will flip out. This feature ensures that the blade is never exposed, it makes sure that you won't damage the key by mistake and it saves pocket space.

push-to-start-car-keys

6.7.Proximity Key / Smart Card

A Proximity Key same as the "Smart Card" is an advanced transponder car key that allows you to enter, start, and drive your vehicle without physically inserting a key into the lock or ignition, your key just has to be near the vehicle for you to be able to open it. Typically vehicles equipped with this type of key have a Push To-Start-Button instead of an ignition lock cylinder. This technology has become increasingly popular in modern cars, particularly those in the luxury and higher-end segments.

8.Fobik Chip Keys

A Fobik remote key is a type of electronic car key commonly used in Chrysler, Dodge, and Jeep vehicles but could also be seen in Mercedes and Infiniti. "Fobik" stands for "Frequency Operated Button Integrated Key," which refers to the key's ability to use radio frequency to communicate with the car's onboard computer which is called the WIN Module or "Wireless Ignition Node". It has similar functions to a remote head key, but the only difference is that the "mechanical key" or the "emergency key" is hidden inside it.

By having this information readily accessible, the technician can quickly find the right key for your vehicle and prevent any mistakes. Plus, it saves you time in the long run!

Before getting a car key replacement service, be sure to have your driver's license or another form of photo identification, as well as proof of ownership, such as your vehicle registration.

2. Call an Auto Locksmith!

After gathering all the necessary information about your vehicle, it's time to call your local auto locksmith. The best part is that many auto locksmiths offer a mobile service, which means that they send a technician to your location. This is especially convenient if you don't want to spend time driving to a locksmith shop or if you find yourself in a situation where you've lost all your car keys.

The process of getting a replacement key is usually straightforward. The technician will retrieve the original cuts of your vehicle by decoding your old key blank or one of your locks if you've lost your original key. Then, the car locksmith will use a matching transponder type to pair with your new key blank and program it for your car.

3. Make sure you get an invoice.

After the job is done, make sure you get a proper invoice with your key fob. An invoice ensures you can make a warranty claim if necessary. A reputable locksmith company will offer a car owner warranty for a new key fob for up to 2 years.

Can I program my own transponder key?

How easy is it to program a car key?


If you still have a working key (sometimes two keys are required*), programming a new transponder key can be a DIY project. However, if you don't have a working key, you'll need to turn to an auto locksmith who has a professional transponder key programmer to do the job.

Depending on which vehicle you own, a car's individual programming procedures are unique to that specific brand. In cases where programming can be done without a working key, you will be asked to follow simple steps. Let's take GM cars for example: they make it possible to program keys without an expensive key programmer, their programming procedure is as simple as turning the ignition lock with the working key and then the new key.

If the process requires a car key programmer, it's best to seek the help of an automotive locksmith. It's worth noting that in many cases, you'll still need the assistance of an auto locksmith to cut your blank key, so you might as well ask them to program it for you!
