We had a customer in St Helens that had a high security lock on their back door and had lost the key. They were told by another Locksmith in St Helens that they could not open the door to replace the cylinder lock as it was very high security. Our locksmith came picked open the lock with no problem to get the door open and then replaced the lock for another high security cylinder lock.
