Transponder Keys

EKeys4Cars is the number one provider of transponder keys in eastern New England.

The transponder chip in your car key is much like the SIM card in a cell phone. It contains a unique ID number that must be stored in the car’s “contact list.” When the chip is recognized, the car will start and run. If the chip is not recognized, the car starter won’t crank or the fuel pump won’t engage – in effect, immobilizing the car.

Ekeys4Cars carries nearly every transponder key made today. Your key can either be cloned or we can program a new one. There are advantages and disadvantages to both.

If you are cloning a key:

  • The car does not need to be present.
  • The first key price is typically less expensive and the price is the same for each additional key.
  • The cloned key cannot be used as a second key to “on-board” program.
  • The lost or absent key will not be erased.

When creating a new key:

  • The car must be present.
  • The first key price is usually more, but additional keys cost less.
  • Keys with unique ID can be used to “on-board” program.
  • The scan tool programming might erase any or all keys not present.
