BMW Lockout Tip

I got a job the other day from a locksmith technician I am working with to unlock a 97 BMW M3. Thinking to myself it was strange for me that he sent the job instead of doing it himself, he informed me that there is a problem with the job. Apparently, the customer left the lights on and it drained the battery. Once he came back to the vehicle, he could not open it. The problem with BMW's in this situation is that you can use the key to mechanically unlock the door by lifting the handle while turning the key, but without any batter power, there is a part that will break in the handle mechanism.

My fellow technician knew I had better experience and knowledge servicing these types of vehicles, so he sent the job to me and I accepted it. I knew there was a special tool called the Lock-master's Flip Pick for BMW models which was meant to use in these types of situations, but I did not have that tool in my possession. Once I got to the job site I came up with an idea that will help resolve the situation. Although using the key to unlock the door would not be an option in this situation, opening the trunk was possible without causing any damage.

I opened the trunk of the vehicle first. Then I looked for the trunk light under the rear deck. I popped the light out using a small screwdriver. I then hooked up some wires from my service vehicle to the light terminals in order to apply some power. This in return supplied enough power to the vehicle, so we were able to use the key to open the door without causing any damage to the handle mechanism. Once the job was complete, I jumped start the customer's vehicle and send him on his way.
