Soneone put Screw in door lock??

I don't have a Ferrari, yet, saving for years and hope to pick up a F430 next year but enjoy reading the boards. I had a strange thing happen tonight with my car so wanted to get your feedback. I live in Spain, parked my car at a mall outside of Madrid. When I walked out towards the car, I was ~100 meters away I noticed a 5 series BMW that was stopped next to my parked car, rear door open but just sitting there. It was dark so when I got to about 75 meters I hit the unlock button and then noticed someone stand up between my car and the other and get in 5 series and it pulled away. I did not think much of it so loaded the trunk with bags and buckled the kids in the back seat. When I went to open my door I noticed there was a screw inserted in the door lock. By this time the car was long gone so I checked the rest of the car and did not notice anything strange. The car is a BMW 3 series but with aftermarket wheels, coilovers. exhaust, etc...so it stands out a bit. So I went home, found a hex drive and removed the screw which was about 1.5 inches long. It pissed me off that these guys were messing with my car but I am not exactly sure what they were trying to do...not sure if they were trying to break in, steal it, or if is was just some prank where they think if they stick a screw in your door lock that you will not be able to open it? Have you ever heard of someone trying to break into a car by putting a screw through the lock?

I have a FOB so don't ever use a key. The FOB has a built in key that you can separate so I tried that. The screw damaged the lock internals but after a few minutes of back and forth with the key I was able to open the lock so it still works. Luckily, no real damage but more of a question of what they were trying to accomplish since I have never heard of people trying to put a screw through a door lock. They were adults in a late 5 series BMW so it was not just a couple of 13 year old punks doing stupid pranks.

 

Thanks Wade. Looks like I was really lucky to get back to my car right in middle of them trying to break the lock! The timing makes sense b/c I got to the car ~20 mins after the normal time to start dinner which in Spain often takes a couple hours...so they probably figured they were in the clear. Cheers.
