Hi guys the little button inside my key has broken off so when I unlock my car to get inside the alarm goes off till I start the engine. Is there a way to stop the sound of the alarm till I get key repaired as I leave for work at 4am every day and wake everyone up

get out of car with key in hand, close drivers door, open rear door, push drivers door button down, this will lock the car but not activate the alarm.

Thanks red baron so this will stop the alarm from going off when I unlock and open the drivers door?

[The Red Baron]

thats correct. 

[teddington man]

Ok thanks I'll give that a try in abit. Don't want to waking people up this time of morning on a sunday lol

How badly damaged is the key? If it just needs the switches replacing this is quite simple if you are good with a soldering iron (or send me the fob, and I'll solder them in).

What I can't ever find is replacement rubbers - the tat on egay are all too hard/stiff.

Only slightly off topic, but an example of Sod's Law (it never takes a day off).....
Why, oh why whenever you take the keys out of your pocket does the key fob always present itself button side down? Well, 99% of the time, anyway. It is way beyond random chance and I think that there is dark evil at work here!

Try turning the Fob the other way around on the keyring, and then see if it presents itself 99% the right way up.                   Bet it doesn't 

[Bigron]

You win your bet, Zirk - been there, done that!
MY money is still on dark forces......

The Red Baron, thank you as you have also saved my bacon too as well as teddington man. Can I ask however ow do you re-activate the alarm once all is well though?

TheBoy, I have taken my fob apart and the battery holder part just came out. I can see the two points that need soldering aswell as the two locating holes but how do I assess whether the part that has the buttons on is still ok or is that something only you can judge if I would ask you to look at it for me?

With the battery not connected properly in the fob at the minute (I have tried to pack the battery inside the fob with small pieces of paper folded over and over to "pack it out") will the key work starting the car (as in the actual blade) or does the fob do some clever electronic tomfoolery sending signals to various ecu's when you try to start the car?

Belive there is a transponder inside key housing not part of the main circuit board this is what activates /deactivates immobiliser so you should be able to still use the key with out busted circuit connections ie central locking immobiliser different  circuits.

[Broomies Mate]

Yep, the transponder chip which communicates with the immobiliser is a small chip loosely glued to the 'horseshoe' part of the key.  When you separate the two parts, you will see it.  DO NOT LOSE IT.  And, if you can be bothered (please do) liberally coat it in superglue so it will never fall out.

Many, many people open up their key to replace the battery and find they cannot start the car.  This is because the small chip fell out when they have, in haste, replaced the battery outside of the local jewellers or motor factors where they have bought the battery.

When opening the key up to do any work, always do it on the dining room table or somewhere where there is plenty of light.  That tiny chip is impossible to find in a carpark!

Been there and done that : )ex police car with only one key at the time and some distance from home= lowloaded to the nearest VX dealer and a 3 day frigg about while they got the key and car pass sorted out plus a £150 bill at the end of it all,lesson learned....the hard way

Thanks Broomies Mate, I still have the little microchip and wow your are right it is super small, have glued it.
