How to reset a security system on a 2005 Ford Focus after changing out a bad battery.

    Found the problem! The battery terminals were cleaned but not well enough. After a thorough cleaning of all the connections everything worked properly. Not what you would expect from the battery expert that swapped the new battery for the old, original battery that was 5 years old and lasted 231,000 miles.

Try reprogramming it.

1. Turn the ignition from OFF to RUN 4 times within 6 seconds.
2. Turn the ignition OFF. The system will chime to confirm programming mode.
3. Within 20 seconds, press any button on first keyless remote.
The system will chime once to confirm programming.

4. Within 20 seconds, press any button on second keyless remote.
System will chime once to confirm programming.

5. Turn ignition to RUN to exit programming mode.

Advance auto and auto zone sell just the flex pipe. You will need to have someone cut the old one out and weld the new one in. costs about $20 for part vs $300 for pipew/catalitic converter attached.

SOURCE: 2005 Ford Expedition, Battery drained, charging

The "Charging Sytem" includes the battery, the alternator, the voltage regulator and all related connecting wires and cables. If the charging system was tested and it tested "good" then all of these components are working properly.
If your charging system is good and you continue to have a dead battery, then you probably have an "Ignition-Off draw". This means that something is staying on after the ignition is shut off. This could be interior lamps not shutting off due to a bad door switch, or the headlamps being left on, or some other electrical component in the vehicle that is malfunctioning. If this is the case, then you need to have your vehicle checked by a competent Service Technician who, using the proper equipment and techniques, can locate and repair the source of the problem.

Sounds like your immobiliser has a fault and is engaging when it should not be. One of the functions of the immobiliser is to engage when the battery power has been disconnected, this is an anti theft precaution against someone trying to tamper with the electrics when attempting to hot wire the car. Have Ford reset the immobiliser anti theft system.

Battery keeps going out on a 2005 ford focus wagon


have you replaced the battery? If not they do get bad cells, If you have? Do a voltage test on battery before you start it and after, Before should be 12.5 or close to tht, And running should be 14 or close to it, If not bad altenator, If both of those check out? Has the vehical got a stock stereo? Sometimes amps and subs kill a charging system, I`ll be waiting for your repost to continually try to help you. Good luck, Sam
