In short: we replace the cylinder without changing the whole lock — after lost keys, when the key goes in stiffly, or when you want a security upgrade. A locksmith arrives in ~20 minutes, the job costs from UAH 500 and the call-out is UAH 300. We work 24/7 with a written guarantee.
Replacing the cylinder is a quick, inexpensive fix: the lock body and the door stay where they are, and only the keyed core and the keys change. OpenLock locksmiths (Lviv locals, 8+ years of experience, checked against police records) carry cylinders in a range of sizes and security grades.
When the cylinder needs replacing
- Your keys were lost or stolen and you want them useless.
- The key goes in stiffly, sticks or turns badly.
- You have moved in and do not know who else holds a key.
- You want a higher security grade without replacing the whole lock.
- The cylinder spins uselessly or has broken inside.
How we work
- We take the request and agree a time — the locksmith sets off in ~20 minutes.
- We measure the cylinder and select a matching replacement.
- We name the price before starting.
- We remove the old cylinder and fit the new one without damaging the lock.
- We test the key action and hand over the key set and the guarantee.
Types of cylinder
- Key-to-key — the classic option, opened with a key from both sides.
- Key-to-thumbturn — locked from the inside by turning a knob, no key needed.
- High-security — with a dimple key and anti-pick protection.
- With anti-drill pins — resistant to drilling and bumping.
- Anti-snap — the cylinder breaks along a line under attack, leaving the lock working.
What cylinder replacement costs
Replacing a cylinder costs from UAH 500 and the call-out is UAH 300. The price depends on the security grade of the cylinder and the type of lock.
We name the price on site after inspection and before starting. You can choose the cylinder itself from those the locksmith carries.
