Please note it is very important when you move to a new property to get the locks changed as her in Spain you just dont know who has a set of keys the way to really check is if the key slot in the lock is vertical then you should have three keys if the slot is horizontal then you should have five keys if in doubt keep them out by changing the locks as a 24/7 locksmith serving the Costa Del Sol I can help Call me on 657466803
