Modern cars are nearly impossible to start without the proper key. Older car types can frequently be started without a key using a screwdriver. It’s also feasible to hotwire the engine.
If you have a newer car model, you must either retrieve the original key or tow it to a professional locksmith or an authorized dealer.
In this guide, we’ll cover the many choices for starting the car engine and what to do if you don’t have a working chip key.
What is a Transponder Key?
Transponder keys, chip keys, or key FOBs, commonly known, are traditional metal keys with an anti-theft chip embedded in the plastic cover.
The key is one of the layers that make up vehicle safety systems. The easiest way to steal an automobile is to utilize the original key. Like in the movies, the thieves would take keys for a minute and leave imprints that they could later recreate.
To prevent this, manufacturers developed transponder chips. Without one, even a perfect replica of a key will not start the engine because there is no chip to emit the RFID (Radio Frequency Identification).
When the key is inserted into the lock, the automobile determines whether the unique RFID frequency can be detected; the chip within a transponder key generates a very weak signal that can only be registered near the lock. If your automobile has a transponder key, a thief will have no choice except to steal your keys, which you will notice sooner and react to prevent the theft.
How To Start My Car Without Chip Key?
You cannot simply bypass transponder keys. That means you cannot start a car without one. In this instance, only the dealership can assist you by replacing your chip key after scanning your vehicle’s radio frequency identification.
Suppose you have a transponder chip; there is a solution you can try. First, remove your silicone cover using pliers or a screwdriver. Because of the constricted seal, something sharper may be more effective for creating leverage. Now remove the chip from the device. It resembles a clear tube or a black square.
Attach the chip to a piece of tape and apply it to the lock. Try starting your key with a disassembled/new key sans the chip. If the vehicle doesn’t start, reposition the tape and try again. Once you’ve found a suitable spot for your chip, secure it with adhesive.
Because the transponder chip is always close to the ignition lock, any duplicate key will work. Although the drawback is that you are breaking a protection layer, this is not a major issue because your car’s anti-theft systems continue to function as deterrents.
Interestingly, because the proximity of two transponder chips generates interference, it may function as a better security system in some instances.
