If it is true that if you leave the keys inside,
in most cases you can open the door with an x-ray,
But it is also true that it takes a lot of skill and practice to achieve it.

Keys put inside. One of the reasons our clients call us the most is because they have left the keys inside. Many times they tell us that before calling a locksmith they have tried to open the door with an x-ray or a credit card, normally the result is usually the same, useless credit card and / or scratched and half-broken x-ray.
