What is a multipoint lock?

A multipoint lock secures the door at several points at once (often 3 or 5: top, middle, bottom, sometimes sides). It resists lever forcing far better than a single-bolt lock. It is a recommended standard for front doors in Paris.

Do you need a 3-point or 5-point lock in Paris?

A 3-point lock suits most flats. A 5-point (or more) is preferable for ground floors, highly exposed doors or as a complement to door armouring. A locksmith assesses the door and frame before recommending a model.

Can a multipoint lock be installed on an old door?

Often yes, provided the leaf and frame are in good condition. On some Haussmann doors, adaptations (rebates, reinforcements) are needed. An on-site diagnosis confirms feasibility and the quote.

Multipoint Lock in Paris: Complete Guide

The multipoint lock has become the standard for securing Paris front doors. Unlike a simple lock (a single bolt in the middle), it anchors the door in several zones, which makes forcing much harder. Here is what you need to know before having yours fitted or replaced.

How does a multipoint lock work?

By turning the key (or operating the handle depending on the model), several bolts or hooks deploy:

✓At the top of the leaf
✓In the centre (main lock + cylinder)
✓At the bottom
✓Sometimes on the sides (5-point models and above)

Result: the force of a crowbar or shoulder charge is distributed, and the door no longer gives way as easily at the central latch.

3 points or 5 points: which to choose?

3-point lock

Ideal for most flats on upper floors. A good balance of security, cost and fitting simplicity. Often enough when paired with a good cylinder.

5-point lock (or more)

Recommended for:

✓Ground floors and mezzanines
✓Doors opening onto the street or an isolated courtyard
✓As a complement to door armouring
✓Homes already burgled

More points = more resistance, but also more technical fitting and careful frame adjustment.

Multipoint + cylinder: the essential duo

A quality multipoint lock with a poor cylinder remains vulnerable (picking, snapping, bumping). Conversely, an excellent cylinder on a 1-point lock does not protect against lever attacks.

At 247 Serrurerie, we often recommend:

A multipoint lock suited to the door
A high-security cylinder from ~€220 incl. VAT
Optionally an anti-pry strip from €360 incl. VAT

Fitting on old Paris doors

Haussmann buildings and solid wood doors demand experience:

✓Variable thickness and rebate depths
✓Frames that are sometimes tired
✓Alignments that have shifted over time
✓Aesthetic constraints in co-ownership

A craftsman checks the frame condition before promising a “standard” fit. If the frame is too weak, reinforcement or partial armouring may be needed.

Installation: the steps

Diagnosis of the door, current lock and risk
Choice of model (3 or 5 points, brand, certification)
Fitting and adjustment of the locking points
Test of opening / closing and key smoothness
Handover of keys and maintenance advice

Typical duration: 1.5 to 3 hours depending on the setup. Quote before work — see also our rates.

Maintenance and signs of wear

Change or have your multipoint lock serviced if:

✓The key forces or spins freely
✓One point no longer engages correctly
✓The door rubs and strains the mechanism
✓After a break-in attempt

Light maintenance (no aggressive WD-40 in the cylinder) extends lifespan. If in doubt, preventive maintenance avoids breakdowns on a Sunday evening.

Multipoint locks and insurance

After a claim, insurers appreciate detailed invoices mentioning the lock type and cylinder. Multipoint equipment + a certified cylinder can also help with some contract negotiations, depending on the company.

Brands and certifications: reading a product sheet

Without getting into a catalogue war, check:

✓Compatibility with your door thickness
✓Ability to take a standard European cylinder (easier to replace later)
✓Anti-drill / anti-pick options on the case
✓Manufacturer warranty + fitting warranty

Beware of low-end “multipoints” sold without professional adjustment: badly fitted, they give false security and strain the door.

Progressive budget (realistic strategy)

If you cannot do everything at once:

High-security cylinder (~€220 incl. VAT)
Suitable multipoint lock
Anti-pry strip (€360 incl. VAT)
Door armouring on quote

This staged upgrade is common among Paris tenants and first-time buyers.

In summary

The multipoint lock is the foundation of a secure entrance in Paris. Choose the number of points based on exposure, pair it with a high-security cylinder, and entrust fitting to a professional who knows the Paris housing stock.
