[ozzy_c180]

Hi,
Thankyou for the help so far!
I have a c class 1999
Problems
Key does not open central locking
When in ignition - nothing happens.. ie steering lock does not even release..
I have tried the key with a digital camera... seems to be sending a signal
(I dont have a spare key)
I have even taken the key to an electrician who claims he has re-soldered
every chip on the board...
I have today replaced the main battery... lights etc come on..

However,
Hazard lights do not come on.... neither does it indicate..
The other day when i had the car on jump leads, the steering lock released but the key didnt turn any further.
The car seems to be dead...Please help.... Am sure some1 will no the prob...

I guess one should be careful with any modern car with a lot of electronics. What I've done when I've given power from my car to another one is switching my car off first (the other one obviously is already), connecting cables, turning on my car to charge the battery on the other car (the other battery does not get charged well by just connecting it in parallel with a good battery). After a while I stop my car and take the cables off.

This isn't very efficient but very safe. It should work unless the car is frozen, more than it is possible in the UK I believe. If absolutely necessary, start the other car while your car is on, after the other car has started, switch off preferably both cars before disconnecting cables but at least your own car.

Jump leads are ok, its battery boosters that kill ECU's etc.
