Jammed lock
A lock that won't turn isn't always a lock to change. On a multi-point door especially, jamming usually comes from adjustment — and adjustment costs a fraction of replacement.

This is your situation if…
- The key goes in but won't turn, or turns only with clear force.
- On a multi-point lock, one point no longer engages, top or bottom.
- The door has to be lifted or pushed before the lock will turn.
Do this now
- 1Stop forcing: that's what snaps the key or the linkage and turns an adjustment into a full replacement.
- 2Test it with the door open: if the mechanism works perfectly open but jams closed, the problem is alignment, not the lock.
- 3Check whether the door catches on the floor or the frame: a dropped leaf is the most frequent cause.
- 4Describe those two tests on the phone: they determine the job, and therefore the price we quote.
Do not do this
- Don't spray aerosol releasing agent into a cylinder: it dissolves the original lubricant and the mechanism seizes for good.
- Don't persist with pliers or a stiffer spare key.
- Don't accept a full lock replacement without a diagnosis done in front of you.
How we deal with it
The tradesperson tests the mechanism with the door open and then closed, checks keep alignment, hinge play and the state of the linkage. In a large share of cases, adjusting the keeps or lifting the leaf is enough.
If the mechanism is genuinely finished — a cylinder seized internally, broken linkage, a damaged case — replacement is priced first, with the hardware choice explained rather than imposed.
What it costs
| Cylinder (barrel) replacement | €140 incl. VAT |
| Full lock replacement | €220 incl. VAT |
| High-security lock replacement | €300 incl. VAT |
Starting prices including VAT, travel included. The exact amount is confirmed on the phone before anyone travels, and agreed on site before work begins.
Frequently asked questions
My multi-point lock won't engage at the top — replace everything?
Almost never. When a single point stops engaging, the cause is mechanical: dropped door, misaligned keep, linkage needing adjustment. Adjustment costs a fraction of replacement, and we only propose a new lock if the mechanism is genuinely dead.
Will releasing spray fix it?
On a cylinder, no: aerosols dissolve the original lubricant and make seizing worse over time. A dry graphite or PTFE lubricant is the right product, and it's what the tradesperson uses after cleaning.
