In years past the odds against someone else’s car key being able to fit your car were not that great. Today the odds of the key to a newer car fitting your car are very great. The newer transponder or chip key technologies being employed have however made even getting a duplicate key to your car expensive and in some cases very challenging. Automotive key duplication and lock servicing requires more specialized skill, training and equipment than ever before.

Transponder Keys

 

Transponder Keys contain a microignition chip within the key that talks to your car, allowing
it to start. They are programmed to operate only with your vehicle, adding an extra layer of security.

Introduced in 1995, transponder keys use a microchip as an extra layer of security. Programmed with a unique serial number, the chip sends a signal to the engine when attempting to start the car. If it’s the right signal, the engine will return a signal back to the key and then it will start. It does something similar while trying to unlock the car, but the car won’t unlock or start unless it recognizes the signal from the key.

But if the key is in some way damaged or the chip missing, will the car emit a chirping sound to indicate its location, and will the car still operate? The answer to both questions is negative.

Additionally, when you locate the car you will not be able to open it because your damaged key no longer has the necessary exclusive identification-to-that-car digital code. And if you force the door open you will still be unable to drive it because the necessary information is no longer in the key and using a different chip key won’t work either for the same reason. And the processor, whose job or purpose is to communicate with the vehicle’s electronic system, will not initiate spark ignition and will withhold fuel injection. In such a situation you may not appreciate such technology but the upside is that this sophisticated technology is a big deterrent to thieves.

What can you do if you lost all of my car keys?

Lost, stolen or broken car keys are easily replaceable through an Locksmith Philadelphia Now or your car dealership. They will have a new car key cut and programmed to your vehicle. The cost of replacement depends on the type of key required. If you have an older vehicle with a basic key, the cost will be minimal to replace but if your key has a transponder, plan on spending $80 or more if you want the key to work in the ignition and not just open the doors and trunk.Lost, stolen or broken car keys are easily replaceable through an Locksmith Philadelphia Now or your car dealership.

Tip how to get around not buying a transponder key and save money.

How to get around not buying a transponder key and save money.
Anyone who has a vehicle with a “transponder key” knows how expensive they are. They’re about $99 or more.
The transponder part of the key is inside the black plastic part of the key.
Philadelphia Locksmith technicians say that today that you can fix and keep your transponder key under the area where your ignition is and then use “regular” keys to start the vehicle.
So for example you have one original transponder key. you don’t want to pay for another key. So you permanently stick this key near the ignition and buy a couple of spare $3.00 keys. As long as the transponder key is close enough, these “regular” keys will work.
And you already bought spare remote fobs from us and they work fine, so I don’t need the keys to lock/unlock the doors.
Some may have concerns about leaving the key in the vehicle, but my thought is that if someone breaks into your vehicle, they’re going to steal your radio/wallet, and if they were going to jack your car, they’d know how to do it anyway.
