Maybe someone can help.

Having gone on a winter cobweb drive yesterday without any problems, tonight it will not start.
Now I do not use the meta immobiliser and the associated central door locking as it is in a secure property, so rarely use it at all. Today though got in and got no sound from the fuel pump but plenty of cranking. All lights on dash were lit as should be, just no fuel pump noise. Wondered whether it could be immobiliser (even though not on) and noticed when I pressed the fob there was nothing. Not even the doors locked.
So could the problem be the immobiliser or it more likely to be something else? Not checked anything out yet as it was this evening when discovered, but all possible suggestions welcome.

For info I have had the car for a couple of years without problem, the immobiliser also has a small star key although I have no idea where that goes. There is a slot at the side of the steering column but it doesn't go there.

Thank you

Have you got a second set of keys?

You say you don't lock the car or use the immobiliser? In my car, if I just leave the car, ignition off, key out for more than 15 seconds, I have to press the immobiliser button once to deactivate the immobiliser. Then it primes and starts...

Am I missing something?

No I don't unfortunately. Do you think an immobiliser can set itself?

The Meta immobiliser sets itself after 20 seconds in my car and you have to press the lock button on the fob to turn it off or use the overide key in the slot on the right of the column. You say you don't use that so it sounds like it has been disconnected. You need to have a search where to put the "star" key or put up a photo of it so someone can advise.

Its never set itself before, so I assume its been disconnected. Apologise for the poor photo, am I the only one with a key?

That's not an immobiliser key that I recognise. Mine s black and has two electronic pins in it. Photo to follow in due course.

Is your alarm plipper grey two tone and circular? If it is, change the batteries and try again.

Alternatively, what else works with the ignition on? If the answer is "not a lot", see if Paul Daniels is hiding in't boot. Then change the 80 amp fuse. It's in the thick brown live lead coming from the battery. Not the red one that goes to the starter motor, the other lead. It will be wrapped in a black plastic casing. The fuse will be in a black case.

Is it possible that the key is to isolate the siren. Some Meta sirens have there own self contained battery power, and a key is used to isolate this.

I'll check what works with ignition on, the key has Meta moulded on it. I have just ordered two batteries for the remote.
What I don't know is whether the immobiliser can arm itself considering that it never has before.

Hi, I have the car going having spent an hour checking the fuel pump etc. I was sure it was the immobiliser so checking pistonhead threads, I finally banged the underneath of the dash and hey presto!.
What does banging actually do?

Thanks

IIRC it releases a sticking relay in the immobiliser

If it is does anyone know if the relay is replaceable or is it inside the immobiliser itself?

Thanks

I think i read somewhere that it can be done, but also that the unit is sealed by plastic welds,with the relays small and soldered in.

There's a fair chunk of immobiliser in the upper dash above the passenger's left knee. Do you know how to get the dash top off? The key tool is a 10 mm ratchet spanner with a flexible head.

Not sure if the relays are visible or not - someone here will know

There are 2 fuel pump relays, its common for there to be a problem with those.
The collision reset button interrupts the circuit to the fuel pump, reset just in case this is activated.
The immobiliser is separate to the alarm as a physical unit but they are coded together.
You can bypass the immobiliser, but I won't post how publicly.

Have you checked all your fuses, also run a battery live to the pump to make sure the pump runs.

The immobiliser relays are inside the immobiliser unit, wacking the underside of the dash just makes the immobiliser bounce up and down, knocking the relay free. It will eventually stick for good, and even if you bypass it, the other two relays wont be far behind in giving up the ghost.

Done all of the usual and it must be the relays in the immobiliser, which if reading above has been butchered by someone before me. Can you PM so I can bypass until I can get a new system.
Thanks

The component casings on any decent immobilisers are sealed/injected with silicone to stop them being tampered with - not very repairable.
