Question about Vehicle Security Systems

3 Answers

Alarm &immobiliser my alarm fob has broken so i disconnected the earth to shut off the noise. the car wont start on the key but runs normally when bumpstarted. i phoned my local vauxhall dealer about a new fob but the guy said the starting problem was not related to the alarm. I found this somewhat confusing as it started perfectly well before. Any advise would be appreciated. Thankyou.

    Because of the position of the alarm siren i dont think it can be but not sure.

    I havent owned it from new. The siren is under the bonnet above the radiator.

  • pedropony2 Jan 16, 2009

    Bump starting is starting by rolling the car then releasing the clutch whilst in gear.

  • pedropony2 Jan 16, 2009

    That was my thinking Te untill the guy at vauxhall said it wasnt.

    Never had a problem starting untill this alarm went wrong.

  • pedropony2 Jan 16, 2009

    Lol bunny can remember doing that back in the day when starter motors were accesible.

  • pedropony2 Jan 16, 2009

    Forgot to mention that i have taken starter motor off and it did run off direct power although somewhat slowly.

  • pedropony2 Jan 16, 2009

    Will try that in the morning as its dark here already.

    Thanks for all your input, will post result asap.

    No probs ed.

    Just thought i would try and shut him up as he is getting on my nerves.

  • pedropony2 Jan 18, 2009

    Have found where the alarm is spliced into the harness behind the glove box. Have reconnected these and still wont start on key.

    Have a nasty feeling this could be a problem with electronic ignition as the wife now tells me she smelled something burning the day before this all happened. Will there be a fuse for the ignition that i can check?

  • pedropony2 Jan 19, 2009

    Armed with all this info i phoned a local auto tech who has disconnected the alarm from the ignition system and all is well.

    Many thanks for all your help which as always was spot on.

    @ Pedro....Please ignore Ginko. He is feeding on responses to continue his rants. This request comes from Lauren. Thanks.

    PP2 - Get a 12 volt testlight, and unplug the small wire off of the starter. Hook the testlight to the battery earth terminal. Touch the pointy end of the test light probe to the small unconnected wire end, the metal part....

    Turn the key to start. Does the light illuminate?

  • Toyota Ed May 11, 2010

    PP2 - I do not agree with the guy at Vauxhall.



    Question: Can you see the starter motor, when the bonnet is up?

    it still applies to newer cars... i'm presuming by what you are saying that you cannot see the starter for some reason ?

    I have an old fashioned idea... have someone try to start it and smack the starter with a hammer... anything ?

    If you can bump-start it, that indicates that the "start" signal from the keyswitch is not being sent to the starter motor. The security system that you have described may just be the culprit. Some security systems inturupt the start signal, to prevent theft.

  • Toyota Ed May 11, 2010

    I would guess that there is something connected between the ignition switch and the wiring harness in the dash. What I would do, Pedro, is to pull the bottom dash panel off, and look at the wires that go to the ignition switch. See if there are some wiring that is connected between the dash harness and the ignition switch. If there are wires between the connector from the dash to the ign switch, follow them until you come up to a box of some kind. Then let me know what you see.

    define bumpstarting... do you mean when someone gives you a boost from their car battery ?

Chances are you need to replace the starter then... if it runs slowly with no load... it likely won't even turn the motor

    Something i might add.... ed is very good at what he does. so weigh the information from the dealer who wants to make a profit and ed who is offering you his knowledge without hopes of compensation

The security system is shutting down the starter. is it factory alarm?

Posted on Jan 16, 2009

    if it is aftermarket alarm, under the dash you should see where they spliced into the starter wire coming out of ign just hook this back up.also look under dash for a small button this is the valet switch and if you push it it should reset and let you start. At least this is the way it is done in usa most of time

  • TripleTauto
    TripleTauto Jan 18, 2009

    have you checked the signal when in start position like ed said? the burning smell could be something in ign switch.i dont have any diagrams on this car so all i can tell you is to check the starter signal coming out of switch and if you have a signal there keep checking down the line till you lose it

Clifford g5 alarm how do i reset it after i was checking fuses it wont let me start the car


The car won't start because the Clifford alarm has a starter interrupt wire where the start wire runs through the alarm system module/relay. The unit then must still be active for the car not to start. If pressing the disarm/unlock button on your Clifford key FOB does not turn the system off, you will after to do it manually. You will need to locate the manual override button installed somewhere in the car that is connected to the alarm system. Turn the ignition switch to "on" or "run" and within 10 seconds press the manual override switch. That will turn the alarm system off and allow the car to be driven normally. I would then take the vehicle to an authorized Clifford or other DEI (Viper) install shop and have them diagnose your apparent problem.

ROVER 600 IMMOBILISER BYPASS


Can I get a replacement Alarm key fob for my Rover 600 series , Factory fitted alarm, Thankyou

1 Answer

Renault Scenic keyfob keeps conking out; as if battery in fob runs down very quickly. So wont unlock doors and turn off immobiliser.


one possibility is that the contacts inside the key are shorting out, consuming new batteries in a few days. A more common problem, is storing the key in a place where the button is constantly pressed in, such as a crowded handbag, pockets in tight jeans, or a keychain full of keys, where it is easy to press them together. If not the case, maybe the car alarm receiver unit is not working properly, and only a dealer will be able to check on that.

Rover 200 fob will not lock/unlock or disarm the immobiliser is there anyway of bypassing it?


Hi, I have a 1999 reg Rover 200 1.4. When I bought the car it did not come with a fob. To cut a long story short, the battery went flat and now I cannot start the car with the key. Is there anyway I can start her without buying a fob? Cheers :o)

I have a sola-larm 835T, the alarm is not recognising or responding to the signal from the key fob transmitter.The alarm is armed and i cannot cancel the immobiliser.New batteries are fitted. Any idea's...


You need to disconnect Battery. On reconnecting, you will hear a "chirp" from the Alarm System. Within 2-3 seconds, press the button on your transmitter, and you should hear the Alarm respond correctly.

Alarm wont shut off and lights keep flashing


This can be very simple look for alarm brain and unplug the brain, this vehicle should start. if it doesn't the look for valet switch it usually mounted under dash or on kick panel next to hood lever or close to where clutch pedal will be, Turn Ignition ON and in ON position flip switch the led light should stay on steady then the vehicle will start. If None of this works then you will have to take panel under steering column down and disconnect complete alarm system. Disconnect wires one ar a time and re-join them with the correct ones. It's NOT hard to do, there will be spliced into ignition wires.To do this you should disconnect positive lead on battery pole to stop the annoying noise until you are done. Good luck and contact if you need more help. Thanks for using FIX YA
