Transponder keys were an innovative and successful form of automotive theft when they were developed over twenty years ago. Keyless entry systems have overtaken the automotive theft protection market in recent years, but there are still many vehicles with transponder key systems on the road all across Georgia, including in East Cobb. As these vehicles begin to age, transponder key systems have started to degrade, and the problems listed in this article have become more common. Transponder key issues can be serious enough to keep you stuck in your tracks, but it doesn’t have to be that way for long. Read on to learn more about transponder keys and what you should do if yours is giving you trouble.
Transponder key technology was originally developed for the aviation industry, but many years later found its way to the automotive industry. Transponder key technology was widely adopted in the 1990s as a response to an increase in vehicle thefts and related crimes. Transponder keys look much like a regular vehicle key, however, they usually have a plastic key fob (head). That addition is not just for looks or to give you a better grip, though. Inside a transponder key’s fob is a microchip that is specially programmed to be linked to the vehicle it is associated with.
When you insert your transponder key into your ignition lock, a signal is sent rapidly within seconds between the two components. Your ignition system has to recognize the coding sent by the key and vice versa. When this process happens, the engine’s computer disables the immobilizer and allows the engine to fire up. All of this happens very quickly and usually without the driver realizing this process is taking place.
As you can imagine, if something breaks down in this process, it can cause operating problems with the vehicle. For example, if something happens to wipe the programming from the microchip, the vehicle will no longer recognize the key and will refuse to start up, even if there appears to be no visible problem with the key upon inspection. While signs of a transponder key issue may not always be obvious upon first glance, by referring to the following guide may assist you in determining the root cause of a problem and determining whether or not you need to call in a professional.
1. You Observe Damage to the Key Fob
Whether you accidentally dropped your key from a high height, such as off of your balcony, or you merely stepped on it at the wrong angle, visible damage to the plastic head of your key often means the chip inside is also damaged. It might not automatic mean this, however, so even if your key seems mangled, it still pays to not assume it’s worthless and try to operate your vehicle. Of course, even if the key works, there’s no guarantee that it won’t deteriorate fast, so it’s always best to have a damaged key replaced. This goes for damage to the teeth of the key, as well, as not only can that make your transponder key stick in the ignition lock, but the lock cylinder itself can be damaged by broken or bent teeth.
2. The Ignition Won’t Fire When You Turn the Key
If your key fits into your ignition cylinder and seems to turn like it normally does without obstruction, but your vehicle refuses to fire, it may be the case that the transponder chip inside the key has lost its programming or that it has become scrambled. Your transponder key will either need to be reprogrammed or replaced in order for you to continue using your vehicle, assuming you don’t have a spare handy. You don’t have to contact a dealership, however, as many locksmith companies are capable of performing this service on a 24 hour basis at an affordable price. Make sure you don’t try to force the key, as this is ineffective and may cause the key to snap off in the lock.
3. The Ignition Cylinder is Jammed
Usually this can occur if dust or dirt from the air or on your key gets inside the cylinder and compacts as you use your key. If you ever use your key for other purposes than what it’s intended for, such as to open packages, grime can collect on the teeth of the key, which can then transfer into your key cylinder. It’s recommended never to use a key for this or any other purpose that does not involve your vehicle. It may also be helpful to clean out your ignition lock occasionally with a can of compressed air to keep it clear.
4. Your Transponder Key Gets Lost or Stolen
While this is obviously not a problem that is limited exclusively to transponder keys, a transponder key going missing or getting stolen is a bit more serious than a simple type of key. A house key is very easy to duplicate, but a transponder key requires specialized equipment and training to make a copy. The price for transponder key programming can vary widely, too, depending on the service provider you choose to have the service performed.
5. Your Transponder Key Only Works Intermittently
This last problem can also be attributed to an issue with the programming. It could also be caused by a malfunctioning in the wiring that connects your ignition cylinder to the vehicle’s computer, or the internal antennae.
