Can security locks be fitted on aluminium doors?

Yes. There are locks designed for the narrow profile of aluminium and uPVC doors, and many are multipoint, locking the door at several points at once.

These doors usually come with simple single point locks, and on the coast they are very common: patio doors, terrace doors, bungalow doors or shop doors. That is why they are worth checking.

What can be done:

• Replace the lock with a multipoint lock adapted to the profile.
• Fit a security cylinder of exactly the right size, so it does not stick out.
• Add an extra lock on doors you do not use to go out.

On aluminium you have to measure carefully and work with care so as not to damage the profile. It is also worth choosing parts that stand up to salt. More in aluminium and uPVC locks.
