You should get a spare key while you still can make a copy of the one you have now.
The chip is in the black plastic part of the key and sends a signal to the security system on the car to allow it to start.
Some locksmiths and the dealer can make you a new key with the correct chip. A key without the chip will not allow the engine to start.

The chip is in the key. Either the key has lost it's program or the transceiver is not recognising the key. Try another key if you have one.

Can anyone help me out I lost my only key of Jeep Grand cheeroke limited 1999. I had one replacement but it's not with a chip.the Jeep starts up and goes off.Any solution to bypass this system please.

A question often asked, so I wrote this :>)

Want to bypass your vehicle security system?

The short answer is you can't!

All modern cars have alarms and immobilizers. There is a chip in the key and a chip in the ignition lock. If both are present, the ECM (engine control module) releases power to the ignition circuit. When you turn the key, the starter spins the engine and you get a spark. If any one of those three items are not in the chain, you get the engine to turn, but no spark. There is no way to beat the system.

The immobilizer is in place to stop exactly what you are trying to do.

There is no way you can. The immobiliser is there to stop EXACTLY what you are trying to do. There is a chip in the key, a chip in the ignition lock and if both are present the ECM releases power to the ignition system.

Sorry you can't. Ford's suck because you have to have two keys to reprogram the security to the keys. Last one I had done cost about $200. Dealer only.

I have a 2003 Ford excursion and somebody tried to steal it and break the ignition my key won't work for it and they also broke the transponder module is there anyway to get around that please help

No way to get around any of that. New ignition parts from the dealer and a new key . Extra keys are dealer only since they have chips imbedded in them and need the key code read from the diagnostic port on the vehicle.

Transponder and key

Hi. No this would need to be renewed. I take it you mean the reader coil for the transponder is damaged, as the transponder itself is in the key. If the key transponder is renewed (not the reader coil around the ignition barrel) then the key would need to be coded to the car.

Car wont turn over after replacing ignition switch

Do you mean the key switch. Read this.

HIGH SECURITY 'CHIP KEY' - By now, most people know their vehicle's high-tech keys are expensive at the car dealers- Now, you can get high-tech keys from us at a fraction of the cost. How does the high-tech key work? The key contains a tiny embedded electronic chip called a transponder. Each transponder has its own unique code--it's the key's 'fingerprint'. When the key is inserted into the ignition and turned, the transponder is energized and broadcasts its unique code to the car's receiver in the dashboard. If the car's receiver recognizes the code, it will allow the car to start. it is the ignition switch under the dash on top of the steering column it needs to be adjusted right.Go to and make an account and put in your make and model and click on repair manual it will show you everything on the car but you have to make an account it's free

Your car uses a transonder key, a key with a small chip embedded inside. The transponder is matched to the immobilizer unit in your car. When the key is inserted into the ignition, the immobilizer searches for that transponder, if it's not near the ignition, the car will just keep turning over and not start. Your only real options are to replace the steering lock or buy a transponder bypass unit, which I do not recommend. Just do a google search.
