Lock repair in Barcelona
The latch scrapes, the faceplate shifts or the throw jumps, and the key is fine. We repair what the mechanism allows; a part that does not exist is not invented.

Repair is recovering the throw of a case that still works: strike, faceplate, dirt, a screw that no longer bites. If the case is cracked or the cylinder has broken internally, the useful route is replacement.
The example is €58 + VAT (€70.18) with travel included. If the same visit ends in a replacement, that amount is deducted.
Faults that can be recovered
A latch that scrapes the frame
The leaf has dropped or the strike has moved. Regulation is often enough.
A jumping turn with a good key
A dirty or dry mechanism. Workshop work can restore the throw.
A loose faceplate
The screws no longer bite. It is refixed or the plate is replaced if the holes are oval.
Where repair makes sense
Old wood in Gràcia or Ciutat Vella
Swollen leaves and AZBE. The strike is checked first; then the case.
A flat with a standard case
If the bolt is intact, a new case is not needed.
A shop with daily use
The closing wears. Sometimes it is regulated; sometimes the case is finished.
When we do not repair
A cracked case or a broken bolt
There is no spare part that makes it reliable. Replacement is proposed.
A destroyed cylinder
That is a cylinder change, not lock repair.
Welding a wrecked faceplate
We do not weld or rebuild carpentry.
Mechanisms opened on the visit
AZBE and tenement mortise locks
Cleaned and regulated. A targeted faceplate replacement if the part exists.
Standard ISEO and CISA cases
If the throw returns, it is left. If not, it becomes a lock replacement.
Sample quote
Example: regulation on a Gràcia leaf
Wooden door on a square, scraping latch. Strike moved, faceplate refixed, three test throws. The case was left.
€70.18 incl. VAT
If the case had been cracked, these €58 would have been deducted from the lock replacement.

Symptom → usual job
| Symptom | Usual job | Page |
|---|---|---|
| Key lost, snapped in the cylinder, or will not enter | Opening. If the barrel is beyond use, a cylinder change in the same visit. | Door opening |
| You are locked out late at night or on a holiday | 24-hour call-out. The time-slot supplement is in the night-opening example. | 24-hour locksmiths |
| The key turns but the latch will not throw | Usually the lock case, not the cylinder. Lock replacement or repair. | Lock replacement |
| Keys that have circulated, or a cylinder that turns stiffly | Cylinder change. The case is left if it still throws. | Cylinder replacement |
| A new door, an empty pocket, or a case that needs a new cut | Installation: measure, pocket and fix. It is not a swap in the same pocket. | Lock installation |
| The latch scrapes the frame or the faceplate is loose, and the key is fine | Repair: regulate or unjam. If the case is cracked, it becomes a replacement. | Lock repair |
| You want more locking points and the leaf can take them | A security lock (the case). A security cylinder is a different part. | Security locks |
| A shutter, an office or a community portal | The same trade, different coordination: authorisation and trading hours. | Shops, offices and communities |
Frequently asked questions
Can every lock be repaired?
No. A cracked case is replaced. The visit exists so an impossible repair is not invented.
Is there a warranty?
Twelve months of labour on what was regulated. If a new part is supplied on the visit, that part has the legal conformity warranty against the party who hands it to you, not only the manufacturer’s commercial warranty. It does not cover a case that was already at its limit and fails again from an internal break.
Is it faster than replacement?
If the fault is the strike, yes. If a case must be sourced, replacement can be shorter.
Related services
Lock replacement
The case that moves the bolts is replaced. The cylinder is a different part: if only the barrel has failed, the whole lock does not need changing.
Cylinder replacement
The cylinder is the barrel the key turns. It is changed to recover control of the access without touching the case when that case is still sound.
