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

You can't just change parts an expect it to work , software , modules won't let it work . You have to take it to the dealer or have a mobile lock smith fix it , reprogram it ETC...

Transponder Chip Key Bypass How To For Any Car

Need more info on what make of car , BUT if it's a Gm some gm's you can bypass..

you can Ohm out the GM key and go to radio shack for resistors

And add them to the little yellow wires at the base of the steering wheel behind the dash,

if you have the right Ohm set up you can drive with any plain key no transponder needed. on some gm's..

no it won't, there is a transponder, a good locksmith will be able to remove the broken key from the lock and reset your transponder from the old key

the taurus is equipped with a pats key system that has a key that communicated to the anti theft transponder. if the transponder, which is mounted around the ignition lock cylinder was damaged a it will need a new tranponder and a new set of keys . you will however need the dealer to program the keys. if you have tow keys now you might try getting those programmed first. if that does not work it will need a transponder nad keys and even possably a pcm

take the chip out of the old key and fit it into the new key if possible ,if not then tape old key behind the shroud next to transponder and it will work till you can get the new keys programmed in the dealer ,now on some of these older models but dont quote me ,if you put the new key in the ignition and open and close the doorlock with the original key it will programme the new key but this may only be on europeon models

YEP YOUR KEY TRANSPONDER IS READ THROUGH THE KEYLOCK CYLINDER READ COIL BY IMMOBILIZER CONTROL MODULE BEFORE CAR WILL START.IF CARRIER FREQUENCY SIGNAL IS NOT 100 - 150 KHZ RANGE CAR WONT START.YOUR CAR HAS TRANSPONDER KEY.MOST ALL LATE 96 TO 2011 VECHICLE CAR KEYS HAVE TRANSPONDER KEYS TO STOP CAR THEFTS.

the lock surround has a transponder built into it that recognises the key(you must use the key to start and run the engine)only answer is a new barrel and recode the keys.and no you cannot deactivate the immobiliser........

the easiest way is to remove the whole ignition swith which requires security star bits the ones with the holes u can get them at some auto part stores or harbor freight. once out find the movable pin put the key in and turn the key till the pin will push in and the tumbler shoud slide right out, its been a while so i cant remember the position just play with it

the anti-theft light is supposed to blink when the car is locked to show the system is armed.

Does it flash while driving?

Principles of Operation
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 out of over 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a driveaway theft. This system is known as Securilock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. Passive means that it does not require any activity from the user.
The SecuriLock® System (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. If equipped the remote start system must be removed before investigation of PATS-related, no-start issues.
Each encoded ignition key must be programmed into the vehicle's powertrain electronic control (PCM) before it can be used to start the engine. There are special diagnostic repair procedures described in this section that must be carried out if a new encoded ignition key is necessary.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to the vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special Unlimited Transponder Security Key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected Security Key is acceptable. Refer to Unlimited Key Mode Programming in Key Programming Switch State Control in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends 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 the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the 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.
The PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS concern, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
The following will activate the PATS and will disable the vehicle from starting:

• incorrectly encoded ignition key
• damaged encoded ignition key
• unprogrammed key
• non-encoded key (key has no electronics)
• damaged wiring
• damaged transceiver
• damaged PCM
