[Mechanics] Locking cars bug

[Letoo]

Description:
When you use a lock on a car while having more than one lock in the inventory all locks will dissapear.

Step to reproduce:
Get 2 or more locks in the inventory and use it on a car, you'll successfully lock the car but all of the locks will be gone.
