Default Loked out of car - ideas to get in

I'm locked out of my e36 m3 and i'm running out of ideas as to how to get into it short of smashing a window.

Some years ago I reshelled the car, i didn't change the locks barrels in the doors and it's now bitten me in the arse. To make matter worse i think i binned the door keys in error thinking they were for another car.

Recently I stripped out all of the interior in preparation for paint. In doing so I have flattened the battery to a point that the central locking has cleared the key programming.

I removed the trim in the boot and the boot light switch didn't depress fully so the light stayed on and the battery ran totally flat. I only figured this out when i fitted a new battery and had the sense to check it.

I can get into the boot and to the central locking solanoid.
I wondered if i could trip the central locking by sending a feed down one of the wires with a power probe. I havn't tried this yet because i don't want to fry any of the control units and i don't have any knowledge of the wiring.

It's a saloon with a ski pack (which I've removed) that's how i managed to get onto the door handles from the boot.


To summarise;

The car won't open on the key, even with a fresh battery.

I have the key for the boot and the ignition but not the doors.

I can access the boot. I can't get into the car or under the bonet.

I have been able to get a hook onto the door pulls via the boot but the doors won't open at all from the inside.

I have also managed to get some fishing line tied onto the lock pop up's but that doesn't open the doors either.



I would appreicate some ideas before i put a brick through the window.

cheers

I think there is the "double lock" signal in the boot lid lock wiring. (double lock means you can't open the locks from the inside). Would need to check the wiring diagram for it.
But that's where I would start ... wiring diagram to see what's available to you.

Ski pack ... hmm, so does that mean you have the rear folding seats? Is there any way to gain access to the seat lock?

Is the rear parcel shelf removable? Or the speakers? Dunno if that's any help.

Does the car have an alarm? My car has a Clifford and I can activate/deactivate double locking etc from it.

I had a similar flat battery issue, but I had spare key for the car.

The other thought, and I warn you this is quite out of the box thinking...

Can you somehow open the bonnet, either from inside the car by fishing a hook around the bonnet lever, or from the front by removing a kidney grill and unscrewing the catch.

Secondly, I assume you have the ignition key, can you fish the key into the barrel and switch the car to accessory position.

Lastly. Once access to the engine bay, hook up diagnostics to the car and activate either the central locking module or power window modules to gain access etc.

Very easy to get an e36 bonnet open if you don't mind possibly breaking some of the brittle clips on the grilles.

so,

you are in the boot, with a small hatch through the rear seats open?

The car has full power

the key will operate the boot lock but not the rest?

does closing, locking and unlocking the boot not trigger the rest of the locking, now the car has a fresh battery? It does on my vert, I know cos I just tried it to see.....

You need an auto locksmith, a good one will get in without causing any damage to your car. I'm one, but you're too far from me.

No point in smashing the window, as you still won't be able to open the door.

I could probably get you a number if you don't have any luck

Get the bonnet open. Stick some jump leads on the battery connectors and unlock the car

Easiest way

Huh!? A key should always unlock a car.

I thought you miraculously locked the car with they key inside.

This is even stranger.

Double lock your drivers door with the key as per handbook
Then try the boot

Fairly sure the Romans didn't have spark plugs in their chariots.

They did. But made of clay.

If the central locking system is all hooked up then close the trunk, and turn the key all the way clockwise (or counter?) and hold it there. Don't all the locks pop then?

Shouldn’t matter. Should unlock the car as well. Which lock you use doesn’t matter.

Unleas this is the “trunk logic” in the ZKE that I never understood what it does.

Still, you have a key, it should unlock from the driver’s door alright.
