When you use your key to attempt to unlock the doors of your vehicle remotely, the doors don’t unlock. Here are the 5 most common signs that you can expect to experience if there’s a problem somewhere in your car’s immobilizer system. Like anything else that is electronic, an immobilizer system can malfunction and case some problems for you. Top 5 Symptoms of an Engine Immobilizer System Malfunction The bad news is that if you lose your key fob or the transponder chip is damaged or goes bad, you’ll need to get a new key from the auto dealership which can be very costly. The good news is that this this electronic immobilization system works very well in preventing car theft and getting your key stuck in the ignition is a thing of the past. This security code is random each time you start the vehicle and your key is the only source that can generate the correct token for the vehicle. If the key is not legitimate or there is no key fob or transponder present, the car will not start.
If this security code matches the code in the immobilizer system, the car will be allowed to start. When you put the key into the ignition or have the key fob inside the vehicle (for keyless fobs), the transponder chip inside the key fob sends a security code to the car’s immobilizer system. The inside of the key fob contains a transponder chip. You just have to be inside the vehicle with the key fob in order to start the car by way of an Engine Start button.īefore paying an arm and leg at the dealership, be sure to check out for a replacement key fob at a fraction of the price. Many key fobs on newer vehicles don’t even have a physical key attached to the base. That is why the base of the key contains buttons to lock and unlock car doors, open the trunk, or sometimes even remotely start the vehicle.
The car keys that car dealerships distribute now are basically key fobs or smart keys. If you’ve purchased a car that was made within the last 20 years, then you’ve probably already used this technology without even realizing it. Research studies have proven there are 40% fewer car thefts since immobilizers were introduced into cars.
Its purpose is to prevent a vehicle from being hot-wired and stolen by a thief who doesn’t have a key to start the engine.
