Locks are for friends, not for thieves dear. Pedal lock, steering lock, crook lock all are easily broken by thieves. They place a device on your bonnet and every security system installed gets jammed. They even break your window to get access as well. A steel ruler (futta) is used to open up the door lock (I also use this whenever I forget the keys inside).
Always try to park your car not very far from where you are. Or park it in the paid parking lots. Best of all is to pray to Allah for safety. Nothing else matter.
