No. The suburban didn't get a transponder key until 2007.
I don't program your transponder key. Try taking it back to a garage of the same type as your car e.g ford and they may be able to provide some help.
Locksmiths have transponder detectors that read if a transponder is active within a key. The device we have is called "TD3AII Transponder Detector" by Ilco.
Most General Motors built cars are now using the PK3 Transponder key.
The dealership can generally program a new transponder key based on the VIN. Most good locksmiths can reproduce the key, but would need the original to do so.
A Toyota Matrix transponder key is factory programed. At times this programing can fail. It is a quick process for the dealership to reprogram the key. A lost key and transponder will cost approximately $100 to replace depending on model.
The circuitry for the door lock/unlock may go bad, but the transponder won't be affected. Meaning, you may have to manually open the door lock using the emergency key, but the Key fob can still be used to turn on the ignition. The transponder is a passive RFID chip that gets "queried" when the ignition is engaged. This is the same type of technology used on pets for tracking pets.
the transponder is in the head of the key ther are about 5-7 parts that are conected on the car that control the key and the reading / from a loccksmith
Locksmith or dealer
In the key
Normally it would only cause a problem if the transponder key had severe damage or trying to start the car without the transponder. If the key looks ok and there's no damage to the sstem then it's probably not the transponder system causing the problem. The dealership could figure this out.
