Can You Bypass Transponder Key?

One of the security features of a modern car is the transponder key system. Inside the head of a typical transponder key is an electronic microchip that communicates with the ignition system of the vehicle. If a key other than the one paired to the vehicle’s computer system is inserted into the ignition, the auto won’t start. In order words, the ignition will only start when turned by a set key programmed to the vehicle.
This feature deters hot wiring and other common forms of car lock attacks. Programming a transponder key can be done by a licensed locksmith at a dealership center. 
In case you need an expert remote key programming, the pros at Tampa Locksmith can help get it done. Call us now to find out more about our car key programming.

Why You May Want to Bypass the Transponder System

You may wish to disable your vehicle’s transponder system if you want a remote starter installed, or you want to make use of ordinary spare keys instead of buying and programming more expensive transponder keys. Regardless of the situation, here’s how to disable this ignition security feature.

Step 1
Remove the Key Head
Start by working off the plastic head of the key using a plyer. To do this, hold the metal end of the key with your hand and gently use the plier to pull the plastic head until it pulls off. Another way is to use a blade or utility knife to slice both sides of the rubber head, leaving the top side intact. Then you gently drag and pull the head off the metal part of the key.
 

Step 2

Fit the transponder chip near the ignition

After separating the head from the key, use hot glue to fit the head housing the transponder chip to the underside of the steering column, making sure it’s as close to the ignition as possible. Without having to insert a complete transponder key in the ignition, the proximity of the transponder in the head will allow the metal key to start the car. You can even cut more ordinary keys and use them as spare if you want.

Completely Disable the Transponder Key Technology

In case you don’t want to put apart the transponder key but still want to disable the transponder technology, then use the steps below.

  • 1.    Put your car key into the ignition.
  • 2.    Rotate the key to the “On” position and let it be for 10.5 minutes and then turn the key back to the “Off” position. You may use a stopwatch to get the timing right.
  • 3.    Repeat step #2 two more times, making sure the last position of the key is in the “Off” position.
  • 4.    Without turning on the ignition, remove the key from the ignition. Now you’ve successfully erased the programming sequence of the transponder key.

Warning

As mentioned earlier, the transponder system is a security feature designed to help secure your vehicle from unauthorized and unwanted access. Gluing the transponder near your ignition can slightly compromise your car’s security. On the other hand, disabling the transponder system completely could mean reduced security for your vehicle.
