The push button devise you use to lock and unlock the doors is your Key fob. It has battery's to make it work, they are inside the fob. Think of it as a TV remote, they use battery's to send the signal to the Tv. Same for your Key Fob uses battery's to send a signal to the car to lock / unlock the doors.

My immobilizer does not recognise my key fob

Put key in ignition.
Press unlock button on key fob.
Immobilizer should now recognize it, if it was original fob but car or fob battery was changed or is now low.

Saabs are particular about batteries that are otherwise good, but just below 12 volts.

My key will not start my car,then it wouldn't open the door

This model year comes equipped with Keyless Enter-N-Go, which uses an electronic transmitter in the key fob to communicate with the car. The vehicle's doors will not unlock and the vehicle will not start if the key fob is not matched to the vehicle or if the commonly-available watch battery in the key fob has been depleted. The EVIC will flash a message upon vehicle startup if it determines that the battery in your key fob is low on charge and should be replaced.

To open the doors, try the following:

1. Use the spare key fob that came with the vehicle. If the battery in your main key fob is depleted, the spare key fob's battery may still retain charge due to its much more occasional use.

2. The key fob comes with an emergency key inside of it. To remove the emergency key, slide the mechanical latch on the back of the key fob sideways with your thumb and then pull the key out with your other hand. This key will allow you to unlock the driver's side door and glove compartment. It will not start the vehicle.

To start the car with a severely-depleted key fob battery, try the following:

1. In case the ignition switch does not change with the push of a button, the RKE transmitter (Key Fob) may have a low or dead battery. In this situation a back-up method can be used to operate the ignition switch. Put the nose side (side opposite of the emergency key) of the Key Fob against the ENGINE START/STOP button and push to operate the ignition switch.

To replace the battery in your key fob, try the following:

1. Remove the emergency key from the key fob following the directions above.

2. Using a vinyl spudger tool or a flat-bladed screwdriver, gently pry the two halves of the key fob apart at the indented slot above the slot for the emergency key.

3. Replace the depleted battery with a new battery. Use the depleted battery to visually match the size. The battery is usually available wherever watch or hearing-aid batteries are sold.

4. Snap the key fob back together and replace the emergency key. If the issue is a depleted battery, your key fob should operate normally.

If the issue is not related to the state of the battery, you will probably need to contact your local dealer for service.

2010 Ford Focus keyless entry quit working

Here are a few things to try and get your Ford Key Fob working again:

1) Change the battery
Batteries don't last forever, you'll be surprised how often it's just a dead battery! Click here for a video on how to open a GM key fob, or search our YouTube channel on how to change a battery for your specific year, make, and model!

2) Wipe the board
The board inside your remote can get a lot more filthy than you think! When the board is dirty it can prohibit the contact to the circuit board when you push down on the button. Simply wiping the circuit board off can make your key fob like new again!

3) Get it checked
Go to your local hardware store like AutoZone or Oreilly's. They usually have a RF frequency tester. This little gadget will let you know if your key fob is sending a signal. If it is, you may need to reprogram your key fob to your vehicle

4) The old car battery reset trick
I know this sounds absurd, but it works sometimes and is worth trying. If you exhausted all of the options above, disconnect both terminals on your car battery for 10 minutes. Then reconnect them and try your key fob. This has worked for many people and I have no idea why. If you do, please comment below to explain.

5) New fob!
It might be time for a new key fob! No need to dread over the expensive costs of a new key fob, at Keyless Entry Remote Fob Inc., you can get a refurbished one for a very affordable price! You won't even be able to tell the difference. Just search your vehicle make, model, and year to find your key fob or give us a call at 402-671-5100.

Car will not run. push button light is green. car acts like it hits (starter engages and cranks and cuts off). Car has gas(put 2 gallons in to make sure gage is good. Battery is good.I Even tried to...

The 2006 has an engine imobiliser in the ignition and micro chip in the key fob. There could be a low battery in your key fob. Take your spare key or your good key and hold it right beside the push button when cranking. See if that allows the engine to fire and remain on. If so replace the battery inside the fob. You can do this by pulling the glove box (silver) key from the end of the fob and inserting the tip of the key into its slot sideways to pop open the **** shell housing and expose the internal battery.
Post back with results.

How do you charge the key fob.. The message on the dash saya that the key fob battery is low.

The key fob does not get charged. Instead you replace the battery inside the Fob. if you look behind the fob it tells you what battery it needs for replacement. CR2032
