If you have lost all keys for your vehicle, but your vehicle has no other problems, this plug & play key replacement service is for you. It includes (2) new keys for your vehicle, all necessary programming, and priority shipping for your keys and Immobilizer ECU. When all keys to your vehicle have been lost, there is a better alternative to replacing an immobilizer ecu with a new part from the dealer. Your old unit can now be reprogrammed with new keys, with no further programming necessary - you can simply plug the immobilizer unit back in and drive your car with the new keys supplied. By avoiding the cost of towing, new parts, and dealer programming, you can save hundreds of dollars. Please view our 100% positive feedback at our ebay store, and if you order directly from this website instead of ebay you will save $10.
