SOURCE: How do I get the code to disable security system

TOYOTA codes are virtually impossible to obtain for free from anywhere on the Internet as access is required to the original factory database.

A few of the older ones are hardwired codes and the only place I know  who may be able to help is here

If not, or you are in a rush , it might be quicker to try your Main Toyota Dealer or take it into a Decode Service

I have a 2000 buick century 3.1 my security light still staying on after i changed the key cylinder and the electrical key switch whatelse can that be ??


Having the vehicle checked for codes should have been the first thing done . Security light on ,a code is stored in the control module that controls the anti-theft system ! This is if you want it fixed right !
Important: If the wrong ignition key is used in an attempt to start the vehicle, a Data Trouble Code (DTC) will be set and the Body Control Module (BCM) will not send a fuel enable or starter enable message to the Powertrain Control Module (PCM) for three minutes even if the correct ignition is used.
The Pass-Key II® Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM) dose not identify the use of the correct ignition key to start the vehicle, the (BCM) will communicate a message to the Powertrain Control Module (PCM) which will disable the crank relay and fuel delivery to the engine.
When the (BCM) identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the (BCM) will send a fuel enable and starter enable message to the (PCM) which will allow the vehicle to start.

DTC B2957 Security System Sensor Data Circuit Low
DTC B2958 Security System Sensor Data Circuit High
DTC B2960 Sec Sys Sensor Data Incorrect but Valid
DTC B3031 Security System Controller in Learn Mode
DTC B3094 No Response from ECM/PCM Received

or you can do a by pass that may or may not work ! You could measure the resistance of the pellet on the side of the key , then go to radio shack a by a resistor of the same value ! Then find the wires under the dash that come from the ignition switch ! Solder the resistor into the harness side wires , not going back to ignition switch . The wires break or contacts inside ignition switch do . You could check resistance with ohm meter . Put key into the ignition switch , find those wires i said about before . Check resistance at the wires under dash , is it the same resistance as pellet ?

I need the radio code for a recently purchased XJS Jaguar


As an anti-theft deterrent, Jaguar began installing radios at the end of the Series III era which required the input of a security code to enable the radio to function. While coded radios are a pain, our experience is that they have drastically reduced the radio theft rates in major cities like Atlanta.
When cars with coded radios were first sold, the owner received a pair of plastic cards, about the size of regular credit cards, listing the radio code. When used Jags trade hands, these cards are forgotten and usually are not passed on with the car. And then when the battery dies and is replaced, the radio insists upon being recoded before it will work again.
One tip is that the dealer technicians frequently would write the radio code under the hood of the car in marker. There are also reports that the radio code was on a paper label which was stuck to the underside of the hood when the radio was installed. So if you do not have your code, it is a good idea to look under the hood for the paper label or for a hand-written four or five digit number. You may get lucky; we have known owners who found their radio code in this manner.
To recode the radio once you have the code, turn the car’s ignition on and then turn the radio on until the word "code" is displayed on the radio faceplate. Enter the radio code slowly and deliberately, firmly pushing on each button. If you have entered the correct code, after the last numeral is entered the radio will beep and then begin to play on the last station selected. If the radio has been uncoded for a long time, or if power has been removed from the radio for a long time, sometimes you will be unable to enter what you know is the correct radio code. In these cases, leave the radio powered, with "code" displaying, for an hour or so and then try to reenter the code. The code will usually take after doing this.
It is not possible to guess at the radio code and to just keep trying combinations of numbers until stumbling on the correct code. The radio will accept only three coding attempts before it locks up for an hour. Then you have three more attempts before it locks up for eight hours, then three more tries before it locks up for 24 hours, and so on. The times indicated may not be accurate, but the process is correct as described.
If you cannot locate your radio code, either from the previous owner or from the car itself, the only way to get the security code is to pull the radio to retrieve the radio’s serial number and to request the code from your friendly Jaguar dealer. All dealers have the ability to retrieve these codes, although they will vary in their willingness to do so for individual owners.

Buick century 3.1 2000 security light staying on car wont crank what can that be


It's the anti-theft system . (SECURITY ) Keeps vehicle from being stolen !
Important: If the wrong ignition key is used in an attempt to start the vehicle, a Data Trouble Code (DTC) will be set and the Body Control Module (BCM) will not send a fuel enable or starter enable message to the Powertrain Control Module (PCM) for three minutes even if the correct ignition is used.
The Pass-Key II?® Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM) dose not identify the use of the correct ignition key to start the vehicle, the (BCM) will communicate a message to the Powertrain Control Module (PCM) which will disable the crank relay and fuel delivery to the engine.
When the (BCM) identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the (BCM) will send a fuel enable and starter enable message to the (PCM) which will allow the vehicle to start.
Your best bet would be have it towed to a qualified repair shop !

I have a 2000 pontiac firebird the security light keeps flashing and my car want start unless you cross it over then it will start and run for a couple of seconds then it quits anybody have any ideal


You have two choices ! 1 is take to auto repair shop an have it fixed the correct way . 2 do an anti-theft system by pass , which may not be the problem . These systems do have a problem with the wires breaking at the lock cylinder . When you stick the key into the ignition lock there are two contacts inside that touch the resistor pellet .The resistance of the pellet is read by the BCM ,if correct the vehicle starts , if not the BCM sends a disable signal to the PCM - engine computer to disable the fuel injectors . That's what is happening on your vehicle , starts for a couple of seconds an dies. Fuel injectors are being shut off .

The personal automotive security system (PASS-Key?®) system is designed to prevent the engine from starting if the proper resistance is not sensed from the ignition key. Of the 15 different key codes or resistance values available, only one will work with each body control module (BCM). Once the key code is programmed into the BCM, the resistance value is stored in a non-volatile memory.
The PASS-Key?® system prevents the engine from starting by controlling the starter relay and the powertrain control module (PCM) fuel enable input. If the PCM does not sense the proper frequency signal on the fuel enable input, fuel will not be provided to the engine.
If the wrong resistance value is sensed when the ignition switch is in the RUN position, the BCM will not ground the starter enable circuit and will not output the fuel enable signal for approximately three minutes. The engine is prevented from starting and discourages a thief from trying key codes or resistance values at random.
If the correct resistance value is sensed when the ignition switch is in the RUN position, the BCM will ground the starter enable circuit and output the fuel enable signal. The engine will start normally.
If the PASS-Key?® system detects an open or short to ground when the ignition switch is in the RUN position, the BCM will default to fail enable. Fail enable occurs when the proper key resistance is sensed before the open short to ground occurs. This has to occur for 1 minute before the fail enable is engaged. Fail enable will illuminate the security indicator lamp and allow the operator to stop and start the vehicle until the problem is corrected.
You can test to see what the resistance is with an ohm meter across the pellet on the key . An then find the wires coming out of lock cylinder an see if you read same resistance ,with key in the ignition cylinder . If you do the wires are ok , if not then you can do the by pass . Go to radio shack an buy a resistor of same value an solder it in between the wires of the harness side , not ignition side . But ,if the wires are good an you can read the resistance value ,then you have other problem an need to have Trouble codes checked .

Pulled radio to get serial # and now I can't get the radio to go into code input mode. it just says "safe" and the icon for pause is on


If you've entered a bad code a couple times, you need to wait an hour while the radio and ignition are on. Then, turn on the radio, SAFE should be displayed. Then Press the FM1 button and hold it down, then while holding down the FM1 button, press and hold the AM buttons so that both buttons are held down simultaneously. Release the buttons. Now enter the correct code using the radio pre-set station buttons (one through 4). Button 1 changes the first digit in the code "1"000, Button "two" changes the second digit in the code 1"0" "three" 00, button changes the third digit, button 4 changes the last digit in the code. In most cases the first digit is a 1 and won't need to be changed. You push each pre-set station button multiple times to step through the digits (1-9) to get the correct code displayed.
Code 1246 would entered by pushing button "2" two times, pushing button 3 four times, and pushing button 4, six times.

After entering the correct security code, push and hold down the FM1 and AM button simultaneously as before until SAFE is displayed, then release the 2 buttons, and now the radio should now work.

2000 Mitsubishi Mirage--Changed battery, code displayed on car radio screen; played with entering numbers, pushed the audio button, now OFF is displayed. What to do?


If you entered the incorrect code several times you may have ruined your chances of getting radio to work. On vehicles with anti theft radio when the battery is disconnected or the vehicle looses power the radio licks and to enable it a code is needed. The dealer may be able to help you but they would need certain information. Sometimes the vin of the car or some times the radio has to be removed to get the serial number. But if the wrong code is entered after so many attempts the radio becomes completely disable. To the point where you will not be prompted to enter a code.

How do I get my radio on when I put the wrong code n three times


Disconnect the car battery for 10 mins.
Reconnect the battery then enter the radio code.

When you disconnect your battery and then reconnect itagain, it disables the radio. This is an anti-theft protection for your carradio.
The enable your radio the activation code is in your vehicle owner's manual. Ifyou do not have this code you need to go to your vehicle manufacturer's servicecentre and get them to enter this code for you.

Have a code alarm for car remote dont work and cant disable it. wont start how do i disconect alarm so car will start


Provided that your system is not programmed for coded override, the standard emergency override is as follows:

1. Enter the vehicle (the security system will trigger.)
2. Locate but do not press the valet/override switch yet (it should be a small black button installed under the dash within reach of the driver)
3. Turn the ignition key to the ON position.
4. Press and release the emergency override button (The security system will turn off).
Note: If the automatic arming feature is enabled on your system. The security system will re-arm the next time the ignition key is turn off and the vehicle's doors are closed.


If the coded override feature was enabled by the installing dealer, you will need to follow these procedure:

1. Enter the vehicle (the security system will trigger).
2. Locate but do not press the valet/override switch yet (it should be a small black button installed under the dash within reach of the driver)
3. Turn the ignition switch to the ON position.
4. Within 5 seconds press the emergency override button the number of times corresponding to the first digit of your personal code (Default digit is 1).
5. Within 5 seconds turn the ignition key OFF, then ON.
6. Within 5 seconds press the emergency override button the number of times corresponding to the second digit of your personal code (Default digit is 1).
7. Within 5 seconds turn the ignition key OFF, then ON.
8. If entered correctly the security system will turn off.
9. Turn the ignition key to the OFF position.

If the coded override feature is enabled and the code is lost, the system will need to be reprogrammed by an authorized dealer.
