My 2001 ford focus keeps locking. The power locks automatically lock as soon as I unlock them, barely enough time to open door.


Your Focus may be equipped with the autolock feature. Try this:

To deactivate/reactivate the autolock feature using the power door unlock control

You must complete steps 1-7 within 30 seconds or the procedure will have to be repeated. If the procedure needs to be repeated, you must wait 30 seconds.

1. Turn the ignition key to ON.
2. Press the power door unlock control three times.
3. Turn the ignition key from ON to OFF.
4. Press the power door unlock control three times.
5. Turn the ignition back to ON. The horn will chirp.
6. Press the unlock control, then press the lock control.
The horn will chirp once if autolock was deactivated or twice (one short and one long chirp) if autolock was activated.
7. Turn the ignition to OFF. The horn will chirp once to confirm the procedure is complete.

I have a99 mercury mountier with anti theft problems some times it won't start with out resting the system through the door lock click 3 times what's up?


are you using a copy of the original key

you need to use the original key for the car

Antitheft and Alarm Systems: Description and Operation
ANTI-THEFT
The passive anti-theft system (PATS) uses radio frequency identification technology
to deter a driveaway theft. Passive means that it does not require any activity from
the user.
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a
permanently installed electronic device called a transponder. Each transponder
contains a unique electronic identification code, with over 72 million billion
combinations.
Each encoded ignition key must be programmed into the vehicle powertrain control
module (PCM) before it can be used to start the engine. There are special diagnostic
procedures that must be carried out if new encoded ignition keys are to be
configured.
The encoded key is larger than a traditional ignition key. The key does not require
batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This module is
located behind the steering column shroud and contains an antenna connected to a
small electronic module. During each vehicle start sequence, the transceiver module
reads the encoded ignition key identification code and sends the data to the PCM.
The control functions are contained in the PCM. This module carries out all of the
PATS functions such as receiving the identification code from the encoded ignition
key and controlling engine enable. The PCM initiates the key interrogation sequence
when the vehicle ignition switch is turned to ON or START.
The PATS function uses the PCM to enable or disable the engine. All elements of PATS
must be functional before the engine is allowed to start. If any of the components
are not working correctly, the vehicle will not start.
PATS uses a visual theft indicator located on top of the instrument panel. This
indicator will prove out for three seconds when the ignition switch is turned to ON
or START under normal operation. If there is a PATS problem, this indicator will
either flash rapidly or glow steadily (for more than three seconds) when the ignition
switch is turned to ON or START. PATS also "flashes" the theft indicator every two
seconds at ignition OFF to act as a visual theft deterrent.
The PATS is not compatible with aftermarket remote start systems, which allow the
vehicle to be started from outside the vehicle. These systems may reduce the vehicle
security level, and also may cause no-start issues. Remote start systems must be
removed before investigation of PATS-related no-start issues.

The PATs key is used on the following Ford family trucks and suvs:

FORD: 1996-2001 MUSTANG, TAURUS
1998-2000 CONTOUR
1998-2001 CROWN VICTORIA
2000-2001 FOCUS
2002 THUNDERBIRD
1997-2001 EXPEDITION
1998-2002 EXPLORER
1999 F-250 LD
1999-2001 F-150, RANGER, WINDSTAR
2000-2001 EXCURSION
2001 ESCAPE
LINCOLN: 1997-1998 MARK VIII
1998-2001 CONTINENTAL, TOWN CAR
2000-2001 LS
1998-2001 NAVIGATOR
2002 BLACKWOOD
MERCURY: 1996-2001 SABLE
1998-2000 MYSTIQUE
1998-2001 GRAND MARQUIS
1999-2001 COUGAR
1998-2002 MOUNTAINEER

Additionally, PATs can be found on the follow Ford family cars and mini-vans:

1998-up Contour
1997-up Crown Victoria
1999-up Escort
2000-up Focus
1996-up Mustang and Taurus
1998-up Windstar
1998-up 2000-up Lincoln LS
1998-up Lincoln Mark VIII, Lincoln Continental and Lincoln Town Car
1997-up Mercury Grand Marquis
1998-up Mercury Mystique
1996-up Mercury Sable

Following are the instructions for programming a blank key (you must have at least one working key for this procedure).

The PAT

1. Make sure you have both keys.
2. Turn on car but don't start. Watch "theft" indicator untils it goes out.
3. Turn off and repeat procedure with second key.
4. After "theft light goes out, insert new key and turn on.
5. Wait until the theft indicator goes off and then turn off switch.
6. Wait thirty seconds. New key is now programmed into security module. Repeat for any other keys.


1. Erase any old codes by entering the factory code.(buttons will light up)
2. Press 1/2 button within 5 seconds.
3. Press 7/8 and 9/0 buttons at the same time within 5 seconds.

To set new code:

1. Enter factory code (numbers will light up)
2. Press 1/2 button within 5 seconds.
3. Enter personal 5 digit code(decide beforehand) within 5 seconds of each previous one.
To unlock all the doors,press the 3/4 button within 5 seconds of the driver door unlocking.
To lock all doors and set alarm system,press 7/8 and 9/0 at the same time.
To disarm or reset a triggered alarm,just enter personal or factory code.

Do not set a code with five of the same consecutive numbers. It's too easy for thieves to figure out.

Deactivating and Activating Autolock

To deactivate the "autolock":
With all doors and tailgate closed but NOT locked,and ignition OFF.
1. Enter 5 digit code
2. While holding 7/8 button in, press and release the 3/4 button.
3. Release 7/8 button
The horn will chirp once if the "autolock" was deactivated
or two times if "autolock" was activated.

To reactivate the system,repeat steps 1 thru 3

Alternate Method To Deactivate And Activate Autolock

Do steps [1] through [5] (below) within 30 seconds or you'll have to do it over. If you have to do it over, wait 30 seconds between attempts.
Close all doors securely.

1.Turn the ignition key to ON.

2.Press the power door UNLOCK control THREE times.

3.Turn the ignition key from ON to OFF.

4.Press the power door UNLOCK control THREE times.

5.Turn the ignition key back to ON .The doors should lock and unlock.

6.Press the power door UNLOCK control. The horn should chirp ONCE to confirm successful switching of the autolock system

Troubleshooting:

The engine does not start and LED remains off.
1. Check PATS system fuses
2. If alarm is fitted check if LED functions for alarm: if not check cigar lighter fuse (also used for LED)
3. If not go to main dealer

Engine does not start: LED flashes rapidly Leave ignition on until the LED starts to flash a 2 digit code: (sequence- pause-sequence)
Check the following codes:
Code flashes:
1:3 Key code not received. Is key screened by other keys or objects? Try different key: if okay then first key is faulty. If not go to main dealer
1:4 Partial code only received. Try again. If not okay use different key. If not go to main dealer
1:5 Key not programmed into PATS. Program key as above using master
1:6 Faulty link between PATS module and EECV Go to dealer .

Got a 2003 mercury grand marquis which i bought and didnt come with a remote for the door locks. i have an extra remote from my 2003 ford expedition and need to know how to program it, any suggestions?


usually the truck and car fobs work on different signals. you can get inexpensive fobs on ebay, the car fob will have four buttons with a trunk release button.
once you have the correct fob, its pretty easy.
  • Just remember that you must also re-program your currently working remotes at this time also as if they are new since prior remotes are erased.
  • Max of 4 transmitters can be programmed.
Procedure:
  • Keep the driver's door open.
  • Electronically unlock the doors (Switch on door or working transmitter)
  • 2000-2006: Turn the ignition from OFF to RUN/ON 8 times within 10 seconds, with the eighth turn ending in RUN. If the module has successfully entered program mode, it will lock and then unlock all doors.
  • Within 20 seconds, press any button on an transmitter, and the doors will lock and then unlock to confirm that each transmitter has been programmed. Repeat this step for each transmitter.
  • NOTE: If the door locks do not respond for any transmitter, wait several seconds and press the button again.
  • To exit the programming mode:
    • Turn ignition to the OFF position.
    • Let the 20 seconds expire.
    • The maximum number of transmitters have been programmed.

Hi, I have a 2007 Accord. When I shift into Drive, my buttons autolocks. How to I get them to UNlock when I shift into Park or shut the engine ?


Typically on autolock cars, when you pull the door handle to open it opens without having to unlock it. The auto lock is a safety feature. Some cars will auto-unlock when you stop, but most wont, you have to hit the unlock button. If yours doesn't auto unlock, the only way to change it would to be to install a switch somewhere on the shift mechanism, it would take a while to do.
