dead battery, broken key cylinder
Post by noncents »

Hi everyone, Bad times at the Z4 front, someone tried to steal the baby and messed up the manual key cylinder, DEAD battery so the key fob wont work, and they stole my rims and wheels in spite. I have a 2009 Z4 E89, saw a couple things on YouTube saying that I can run a 12 volt lead to the blinker, or from the plate light to give the car 12 volts to use my fob. will this mess up any of the electronics in the car and most of all will it work? also was told I can remove the grill plates and open the hood that way. any advice would be greatly appreciated. Thank you in advance.

Can't believe no one has an answer to this. Hope you are never in this predicament

Let me be the first to welcome you to the forum and I’m sorry to hear of you problems, this is mainly a uk forum so the time difference between countries won’t be helping, the front grills can be removed by pulling but be careful not to break the retaining clips, that’s the only help I can give but I’m sure someone with more experience will be along shortly to help.

This won't be much help, but BMW says this

Emergency Opening of Rear Lid
As there is no lock cylinder and Bowden cable assembly, the rear lid cannot be released
in the event of the rear lid lock being defective. At the same time, movement of the
retractable hardtop is inhibited by the unknown status of the rear lid.
The lid can be opened if the Bowden cable (emergency glow in the dark) handle can be
reached from the through load compartment.
The rear lid can also be forced to open by using the diagnostic tester. The rear lid activation
via the JBE component activation function. This activation request ignores all status
that would typically inhibit rear lid operation such as top position.

Seems to be a ridiculous design, even if you can get in the car it isn't easy. Is there not a key cylinder on both doors? I've never checked and my car is at the body shop.
There was a similar thread sometime ago, the guy had the breakdown service open the door with some tool I believe.

...DEAD battery so the key fob wont work,...

Which battery do you mention, car's battery or from the key fob?
The car's battery can be reloaded from the "red" charging point below the bonnet. A good BMW mechanics should be able to get it opened from the front.

Might be able to apply positve as the battery cable to front of car pass through the boot floor or the cable to starter motor.
