Lock for all types of domestic doors & windows

Enjoy a fast, professional locksmith service from a local, friendly team. Whether you want your lock changed or upgraded, Doncaster`s expert locksmiths are here to help.


For wooden doors, we recommend using a mortice deadlock (also referred to as a ‘Chubb’ lock) and a rim night latch (also known as a ‘Yale’ lock). These British Standard (BS3621) locks meet insurance requirements and provide enhanced security for your peace of mind.

uPVC or composite

A multipoint locking mechanism and a compatible Euro cylinder are required. For insurance purposes, the multipoint locking mechanisms must have multiple locking points to comply with most policy requirements. This number has changed, and recently, we have seen it reduce.


The lock will be morticed into the door and generally be a standard or multi-point sash lock. Insurance policies require typically suitable dead / sash locks and sometimes additional internal locking bolts fitted on top and bottom.

Sliding patio

Our services extend to sliding patio doors as well. We can install additional locks such as patio door bolts in the top and bottom corners of each door. These bolts, when the central lock is broken, provide an inexpensive yet effective solution for securing your sliding patio doors.

Your local commercial locksmith in Doncaster

The vast majority of locks fitted to commercial and industrial properties are not available at your average DIY shop. Therefore, it is recommended that you employ a company with expert knowledge of the correct locks to fit when required.
