This sounds like a fault in the system. If it is an after market product you can try a rest after checking all lines, connectors, splices or fuses that may be installed. If it is part of the included equipment, a common item in today's vehicles, you will need to have the dealer check it with their ECM computer. Toyota incorporates Alarms in the ECM when they install them as part of a vehicle line. In those cases it is very difficult to isolate problems in the alarm system itself and if the fault is an ECM issue the problem will migrate to your other systems leading to ECM replacement after warranty has expired. Being a 2008 you need to get this into the Dealer and have it checked and replaced while it is under warranty. ECM on this vehicle run over $2000 when I last checked.

My 2002,ford focus se 5 SPD won't start at all no sound when key is turned. When key is in start position no dash lights come on and my anti theft light above hazards blinks continuously any ideas?


Verify battery condition by turning on headlights and seeing if they are bright. If ok, the theft system may be activated. Try locking and unlocking doors with the key fob. This will usually reset the theft deterent system.

Dealer gave me a shaved key works on starting ignition not on door lock the other three keys work on everything car doesn't have engine immoboliser removed the remote keyless entry fobs what is


Many times the dealer gives you a valet key made to give to the vet to park your car, these keys work even though the theft deterant system is active, but they will only work for short periods untill the theft system activates and imobolizes the vehicle. The system is reset when the valet brings your vehicle and you insert your normal (chiped) key.

Anti theft light comes on the car won't start


Your "inmobiliser" system is actived.

The anti-theft feature prevents the car from being started when one of several anti-theft devices is faulty are have otherwise been activated. The problem you descibe might be the ignition swith, which is known to wear out quickly on those models. The system can be completly disabled only when the car is running (meaning the teft deterent system is inactive after the Passlock II system detects the proper key in the ingition). A wire can be cut that would perminantly disable Passlock II, meaning any key that opens the door (or a screwdriver) could start the car. If the ignition swtich goes out or this wire is cut while the engine is off (theft deterent system is active) then the car will have to be towed back to the dealer to have the ignition system replaced and reprogrammed.

I have called Chevy and asked how to fix this problem. If you turn the key to the on position, right before it cranks when the lights and radio turn on. Leave it there for ten minutes until the anti theft light turns off. Then turn the key to the off position and then try starting the car.

Rumour has it that it is a yellow wire to be cut. Do more research, but D O N ' T cut it with the engine off. See first paragraph above.

Hope this help (remember rated and comment this). Good luck.

The maintenance required light has come on and we have just had the oil and filter changed. How do we reset the system. I have a 2008 Toyota Sienna.


Key in the off position, press and hold odometer button, turn key on. If done properly, you will see dashes on odometer, they will disappear in 10 seconds. You may now remove finger from button. The system has been reset.

Your key has to be able to communicate with the receiver in the ignition area. Does your other key work ok?

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.
  • During each vehicle start sequence, the ignition key identification code is requested by the PATS module.
  • If the key's ID code has been programmed into the system, the vehicle powertrain control module (PCM) (12A650) is allowed to operate; this allows the vehicle to start.
  • If the key's ID code is not programmed into the PATS module, or if no encoded key is detected, then the vehicle PCM is disabled.
The PATS module, located under the driver side instrument panel, communicates the state of the security system to the PCM via the module communications network. The PCM, based on the communications from the PATS module, will determine if the vehicle's engine will be enabled to start. If the PCM prevents the vehicle from starting because of PATS, the PCM will store a DTC in memory.
-------------------------------------------------------------------------
The anti-theft vehicle protection system utilizes the THEFT indicator, located in the instrument cluster (10849), when the ignition switch is turned to the RUN/START position. The indicator provides system prove out and operating status to the customer or technician.
Each PATS ignition key holds electronics that give each key a unique ID code.
The PATS will activate the indicator signal when the ignition switch is turned to the RUN/START position. The THEFT indicator will turn ON for two seconds, then turn OFF.
If the THEFT indicator flashes for one minute or more, this indicates that there was no key code received.
When the vehicle ignition switch is placed in either RUN or START, the PATS module requests the ignition key ID code. The PATS module requests the ignition key ID code by supplying power, ground, and the carrier signal to the transceiver to energize the ignition key. After the energize period, the key transmits its ID code to the transceiver module, which sends it to the PATS module.
The PATS module then compares the received KEY ID code to those stored in memory (16 maximum). If the ID matches, the PATS module sends an enable signal to the PCM over the module communication network.
The passive vehicle protection system utilizes the engine management capabilities of the PCM to enable or disable the vehicle engine. The module communication network is used to send and receive messages to and from the PCM.
Within one second after engine start, the PCM must receive an enable signal from the PATS module through the module communication network or the engine is disabled before the vehicle can be moved.
If the PATS module recognizes a stored ignition key code but there is a module communication network concern preventing the PCM from recognizing the start enable signal from the PATS module, the vehicle engine will be disabled. If this happens, the PATS module will flash the THEFT indicator for one minute, then flash diagnostic trouble code 16 ten times to indicate there is a problem with the module communication network circuits or the PCM is not responding properly.
The passive vehicle protection system will disable the vehicle from starting if there is a:
  • Damaged encoded key.
  • Unprogrammed key.
  • Non-encoded key (key has no electronics).
  • Wiring concern.
  • Transceiver concern.
  • Control module concern.
  • Module communications network concern.

The problem is the new PCM you installed does not have the correct VIN number of your car.
You may be able to relearn the VIN using the preceedure below, however, there is no gaurentee it will work. You may have to have a dealer reset the VIN for you by way of a scan tool.

1) Instert key into ignition and rotate to run position (do not try to start engine)
2) Leave the key in the run position for 10 minutes until security light stops flashing.
3) Turn ignition key to off position for 10 seconds ( no more, no less)
4) Turn ignition to run position again for 10 minutes until security light stops flashing and repeat step 3 and 4 for (1) more cycle.

The process is a security verification step for the VTD system. ( Vehicle Theft Deterent)

Give it a try, let me know.
