What if my Avantis lock is an older or discontinued model?

Older Avantis mechanisms often have compatible retrofit gearboxes or strips available. We identify your existing setup and fit the closest modern equivalent that works correctly with your door.

Do you offer security upgrades for Avantis doors?

Yes. We can upgrade your Avantis door with 3 Star TS007 anti snap cylinders, reinforced keeps and improved handles to increase security and resistance to attack.

How long does an Avantis lock or gearbox repair take?

Most Avantis gearbox or alignment repairs are completed in a single visit, typically in under an hour depending on the nature of the fault.

Is your Avantis lock work guaranteed?

Yes. All Avantis multipoint lock and gearbox repairs carried out by The Key Locksmith include a 12 month guarantee on both parts and labour.

Can you help if I am locked out due to an Avantis lock failure?

Absolutely. We provide a 24/7 emergency locksmith service across Orpington and the surrounding areas for Avantis lockouts and failed mechanisms.

Avantis Multipoint Locks & Gearboxes

Q: Can you replace just the Avantis gearbox?

Yes. In many cases only the central Avantis gearbox has failed. We can replace this part on its own without changing the full multipoint strip, which keeps the repair quick and cost effective.

Q: Can you open a jammed Avantis lock without damage?

We use professional non destructive entry methods wherever possible to open jammed Avantis locks safely, then repair or replace the faulty components once the door is open.

About Avantis Multipoint Locks

Avantis locks are known for their robust, high-security multipoint mechanisms used on uPVC, composite and aluminium doors.
Each mechanism uses multiple hooks, bolts, and rollers along the door edge for maximum strength and weather sealing.

The main working part is the Avantis gearbox, which drives the locking points.
When this gearbox starts to wear out or fail, you’ll notice:

Handle feels heavy or stiff
Key won’t turn fully or gets stuck
Door needs lifting or pushing to lock
Lock jams or works intermittently

These are warning signs that it’s time to have the mechanism checked before it fails completely.

Common Avantis Lock Problems We Repair

Handle floppy, stiff or not springing back
Key turns but door stays locked
Door needs force or lifting to engage locks
Lock sticks more in cold weather
Gearbox cracked, jammed or broken

We can often repair your Avantis mechanism without replacing the entire lock or door, saving you money and downtime.
