Open lock cylinder on a bench for repair in Barcelona

Lock repair and maintenance

When the key is stiff, the bolt will not throw or the cylinder creaks, we repair or maintain it before it stops opening.

A lock that is caught in time stays. We clean, adjust and repair home and portal mechanisms. If the cylinder is finished, we propose a change. Maintenance avoids a night opening that costs more than a booked call.

When to book it

  • A key you have to wiggle

  • After a picking attempt

    Check whether the mechanism is still sound.

Frequently asked questions

Does cooking oil help?

Do not use it. The wrong product cakes dust. Better a maintenance call.

Will a repair feel like new?

It will be usable. If wear is total, a change is the clean option.

Do you maintain storeroom or grille locks?

Yes, if they are the same kind of locksmith work we already do.

The key no longer turns cleanly

Ask for a check. Sometimes it is an adjust; sometimes a new cylinder. We say so before we act.
