Question about Volvo S40

1 Answer

Is the car locking system programed into the key or engine software? I had my key socket exchanged recently, after a while I had a message that "immobilizer failed check the manual". The car didn't wanted to go, I turned it off and on and finally I could come home. They told me that I need an engine software update, which I did, but now the central lock doesn't lock the doors when I drive like it used too. Is it possible that they actually changed the key software instead of engine as they told me and charged me for something they should do with the key socket?

Key programming is seperate on older vehicles with a seperate transponder and transponder reader but integrated on newer models ,return car to garage and ask them to look at it again but if it was a software upgrade on the computer then their are new laws within the EEC regarding the self locking of cars and some member countries have been lobying against it and want it removed from cars as its dangerous in a accident ,so i honestly couldnt say as to weither this vehicle was re-programmed to current europeon norms,personally after getting burnt trying to get some kids out of a locked car in a accident and watch them burn to death as the gas tank went up and i couldnt get close enough with anything in my hand to smash the window glass iam in favour or removing self locking doors

Key code


Well you don't actually program the key, you put the car into a condition so it will "learn" the remote to use with it.

Procedure
1. First open a window (just in case) use existing key (if you have one) place in ignition and turn to ON (RUN position), do not start the engine.
2. Use the new key to lock the car, the key not the remote. Now press one of the buttons once on the new key transponder, the lights should flash, wait 10 seconds and press the unlock button, the doors should unlock and the key should be recognized by the car's security system.
3. If you are programming a second key repeat the above but press the remote button twice, three times for a third key.

Alternative Method
Procedure
1. Switch on ignition; system will then remain in programming mode for 30 seconds.
2. Briefly press any button on the remote control unit while the unit is in the ignition.
3. The central locking system locks & unlocks to show that the remote control has been programmed into the car's security system as a valid remote now paired to that car.

OBD2 Stands for On Board Diagnostic Version 2
CANBUS means Control Area Network Bus
CANBUS is a communications protocol that allows devices and computers in a modern car to communicate with each other. It allows modern vehicles to have such functions as increasing the volume of the stereo as you speed up and slowing down the windscreen wipers when the car stops.
OBD2 is a standard for fault reporting and transmitting real time data on how an engine is behaving to an external device connected to the diagnostic port in your car. This may be a handheld OBD code reader device or a laptop equipped with suitable diagnostic software.
If you had a CANBUS capable OBD device connected to your car's diagnostic port then it would use the CANBUS protocol to exchange data with your cars on board computer systems.
With some devices this can be a 2 way exchange and can allow you to upload new engine software for better performance and program some of the other functions of the car like whether the central locking unlocks the drivers door or all the doors on the first click of the remote or requires two clicks to unlock all the doors.

Mazda 6 keyless entry


One of the service writer guys at my local Acura dealer came out and programmed my new key fob on my RSX for me for free. Try that at your Mazda dealership. As I recall, I had to have all of the key fobs I planned to use on that car with me at the same time so that they would all get programmed the same. So bring all of yours with you, just in case.

  • 1 Put the vehicle in park, and turn the ignition to "On/Run" (don't crank the engine).

  • 2 Press the odometer trip stem on your instrument panel until it displays the message "Relearn Remote Key." Then release the stem.
  • 3 Press and hold the odometer trip stem again for three seconds. You will see the message "Remote Key Learning Active."

  • 4 Press both "Lock" and "Unlock" on your key fob at the same time, and hold the buttons down until a chime sounds. This should take about 15 seconds.
  • 5 Repeat Step 4 for each additional key fob you wish to program.
  • 6 Turn the ignition to "Lock/Off."

    Replaced chip on key on 91 DTS and car lost all power while driving. It shut down and nothing works.


    There are 4 methods for programming key fobs. Up to 4 key fobs may be programmed to the remote control door lock receiver (RCDLR). Each programmed key fob is given a position of #1-#4 in the RCDLR memory.
    Method 1 - Key Fob Quick Learn This procedure will add key fobs. Fobs will be numbered in sequence based on when they are programmed; if 2 fobs are currently programmed to the RCDLR, a fob programmed using this method will be numbered as Fob 3. This procedure requires that you have a known good key fob, a replacement key fob, and the vehicles mechanical key.

    Important: This procedure is not available when the maximum number of fobs (4) have been programmed. If 4 key fobs are programmed to this RCDLR and this method is attempted, the driver information center (DIC) will display MAX FOBS LEARNED and the programming procedure will exit. Method 4 must be used in this instance.


    The vehicle must be OFF.
    Place a known key fob within the interior of the vehicle.
    Insert the vehicle key in the driver door lock cylinder located in the driver door handle and cycle the key 5 times within 5 seconds.
    The DIC will display a message: READY FOR FOB X (X = fob 2, 3, or 4).
    Place the replacement key fob in the console fob pocket with the buttons facing forward.
    A beep will occur and the DIC will display: READY FOR FOB X (X = fob 3 or 4) or MAX FOBS LEARNED.
    If programming additional key fobs, repeat steps 5 and 6, or press the OFF/ACC portion of the ignition switch to exit programming mode.
    Operate the active portion of each key fob in order to finalize the programming sequence and verify correct system operation.


    Method 2 - Key Fob Slot Programming

    This procedure will add or replace a key fob. Method 2 allows you to choose which location (slot) the unprogrammed fob will be learned to. If you are replacing a key fob, this method will erase the previously known key fob programmed to that particular slot. This procedure requires that you have a known good key fob, a replacement key fob, the vehicle mechanical key, and a scan tool.

    Important: This procedure is not available when the maximum number of fobs (4) have been programmed. If 4 key fobs are programmed to this RCDLR and this method is attempted, the DIC will display MAX FOBS LEARNED and the programming procedure will exit. Method 4 must be used in this instance.


    The vehicle must be OFF.
    Place a known key fob within the interior of the vehicle.
    Install a scan tool.
    Use the scan tool, to access the following:
    • Vehicle Control Systems

    • Computer/Integrating Systems

    • Module Replacement/Setup

    • RCDLR

    • Program Key Fobs

    Insert the vehicle key in the driver door lock cylinder located in the driver door handle and cycle the key 5 times within 5 seconds.
    Select Fob X (X = 1, 2, 3, or 4) on the scan tool. This will be the slot you wish to program to.
    Place the replacement key fob in the console pocket with the buttons facing forward. A beep will occur indicating programming completion. The previously known fob is now erased.
    If programming additional key fobs, repeat steps 4-8, or press the OFF/ACC portion of the ignition switch to exit programming.
    Remove the scan tool.
    Operate the active portion of each key fob in order to finalize the programming sequence and verify correct system operation.


    Method 3 - Key Fob Auto Learn

    This procedure will first erase all known key fobs. The procedure will then program a single or multiple key fobs. Method 3 is a series of three 10-minute key cycles, for a total of 30 minutes. This procedure requires that you have a replacement key fob and the vehicle mechanical key.

    Important: All previously programmed key fobs will be erased upon completion of the 30-minute programming procedure. The order in which the key fobs are programmed will determine its numbering position within the RCDLR memory. The first key fob programmed will be key fob #1, and the second key fob programmed will be key fob #2. The number stamped on the key fob case is for reference only: #2 can be programmed as #1.
    Do not place any known good key fobs in the vicinity of the vehicle when programming with Method 3. If the RCDLR recognizes a known good key fob during Method 3 programming, the programming mode will resort to Method 1.


    The vehicle must be OFF.
    Place the replacement key fob in the console pocket with the buttons facing forward.
    Insert the vehicle key in the driver door lock cylinder located in the driver door handle and cycle the key 5 times within 5 seconds.
    The DIC will display a message: OFF/ACC TO LEARN.
    Press the OFF/ACC portion of the ignition button.
    The DIC will display a message: WAIT 10 MINUTES, then it will count down from 10 to 0, one minute at a time.
    When the counter reaches 0, DIC will display OFF/ACC TO LEARN.
    Repeat steps 5-7 two more times, for a total of 30 minutes.
    The DIC will display a message: OFF/ACC TO LEARN.
    Press the OFF/ACC portion of the ignition button.
    A beep will occur and the DIC will display: READY FOR FOB 1. At this time all previously known key fobs have been erased. When fob 1 is programmed a beep will be heard and the DIC will display a message: READY FOR FOB 2.
    Additional key fobs can be programmed by taking fob 1 out of the pocket and inserting fob 2. If desired, up to 4 fobs can be programmed. Once 4 fobs have been learned, the DIC will display a message: MAX FOBS LEARNED, and automatically exit the program mode.
    If learning less than 4 key fobs, press the OFF/ACC portion of the ignition button to exit the program mode.
    Operate the active portion of each key fob in order to finalize the programming sequence and verify correct system operation.


    Method 4 - Service Programming System Fob Programming

    This procedure is a 10-minute relearn procedure using the Techline Terminal with SPS software. Once the 10-minute timer has expired, the fobs can be programmed similar to Method 2 using slot programming. A scan tool, Techline Terminal, and a replacement key fob are required to perform this procedure.

    Place the vehicle in the Vehicle On, Engine Off mode.
    Connect a scan tool to the vehicle.
    Insure that all power consuming devices are turned OFF on the vehicle.
    With a scan tool, select Request Info under Service Programming System and follow the scan tool on-screen instructions.
    Disconnect the scan tool from the vehicle and connect the scan tool to a Techline Terminal with the current Service Programming System (SPS) software.
    Turn the vehicle OFF.
    On the Techline Terminal, select Service Programming System and follow the Techline Terminal on-screen instructions. Ensure the correct programming procedure is selected based on component being replaced or programmed. See Important above.
    Disconnect the scan tool from the Techline Terminal and re-connect the scan tool to the vehicle.
    With a scan tool, select Program ECU under Service Programming System.
    At this point the scan tool must remain connected for the duration of the 10 minute relearn procedure.
    When the 10 minute relearn procedure has completed, use the scan tool to access the following:
    • Vehicle Control Systems

    • Computer/Integrating Systems

    • Module Replacement/Setup

    • RCDLR

    • Program Key Fobs

    Select Fob X (X = 1, 2, 3, or 4) on the scan tool. This will be the slot you wish to program to.
    Place the replacement key fob in the console pocket with the buttons facing forward. A beep will occur indicating programming completion. The previously known fob is now erased.
    If programming additional key fobs, repeat steps 12-13, or press the OFF/ACC portion of the ignition switch to exit programming.
    Remove the scan tool.
    Operate the active portion of each key fob in order to finalize the programming sequence and verify correct system operation.
