My car will not always start, someone suggested the chip in the key is not working properly?

I'm sorry, but it is not possible to start a 2005 Ford Focus SE without the key chip. The key chip, also known as a transponder key, is a security feature that prevents unauthorized access to the vehicle. Without the key chip, the car's engine immobilizer system will prevent the car from starting.

If you do not have the original key with the chip, you will need to obtain a new key with a chip from a Ford dealership or a qualified automotive locksmith. They will be able to cut a new key to match the locks on your car and program the new key chip to work with your car's immobilizer system.

Please note that attempting to start the car without the key chip or trying to bypass the immobilizer system may cause damage to the car's electrical system and could potentially lead to other issues. It is important to have a proper working key chip to ensure the safe and reliable operation of your vehicle.

The car not reading the key chip try disconnect the negative battery cable for 30 sec kep the keys alway of the car conect back and try the keys should read and start if not you need a locker Smith to reprogram your keys

The steering wheel lock is simply a physical lock that engages and disengages when you remove the key and turn the wheel. It has nothing to do with the electronic portion of the passkey system.. The transducer reads the chip in the key and sends the proper code to the vehicles pcm/bcm to start the car. The car is still electronically protected from someone trying to hot wire or start your car with the improper key. The steering lock is an additional level of security for the vehicle.

No the key has nothing to do with this. You have a failed display in the instrument cluster. You will need to remove it from the car and send it out for repair. Cost is about $200.00 to repair the problem.

only thing i think is maybe you have more than one key and one doesn"t have a chip cuz my car has a key that will do everything but start the vehicle....and the chipped key that does start it....just a longshot....but true none the less.

You lost the key with the chip in it, you have to get a new key with a chip and get it programmed. I'm not sure what all is involved, but that is the idea. I think Walmart has the key, but they might not be able to program it.

THE ONLY RESOLUTION TO THIS PROBLEM IS TO REPLACE THE KEY CYLINDER WITH A NEW ONE. LOCAL REPAIR GUY IS CORRECT. IF THE TINY SENSOR IN THE KEY SWITCH DOESN'T RECIEVE THE EXACT RESISTANCE FROM THE CHIP IN THE KEY, IT WON'T START. THE TINY SENSOR IS PART OF THE KEY CYLINDER, THAT CANNOT BE BYPASSED. HOPE THIS HELPS. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. BEST OF LUCK. ANY MORE QUESTIONS, PLEASE ASK AWAY.

The most likely cause for the problem you are describing is the anti-theft system. GM calls it a passlock system. Your car has a 'key-reader' mounted on the ignition lock cylinder (inside the steering columnm, or inside the dash, depending on where your key goes). This 'key-reader' sends out a signal to the body control module indicating that the proper key is in the ignition. Note: this style antitheft system does not have 'chip' in the key. These key-readers fail frequently and send a an incorrect singal the the module, where the car will start and run for a few seconds, then stall. An easy verification of this problem is to watch for your security light to be flashing somewhere on your dash. The passlock cylinder is only available from the dealer, and while it is a fairly easy part for someone like me to change, I do not recommend it for someone who is not a mechanic. Additionally, even if you do change the passlock cylinder, you have to perform a re-learn procedure or the car will never start. This probably isn't the answer you wanted to hear, but better that you know. Hope this helps!

the ignition keys are not coded. no "chip" in them you should be able to just have a spare key cut and it will work fine. These use an electronic device in key cylinder that senses the proper rotation of cylinder and tumblers. so if someone tries to pry on with a screwdriver it will disable starter. when this is replaced it has to be reprogrammed

you might have to send it over seas maybe to a key cutter
