Keyfirst : Building Keys - Duplication and Security Solutions

Professional building keys: blanks, dimple keys and accessories Keyline, Silca, JMA, Errebi

This category brings together all building key consumables distributed by Keyfirst: standard flat key blanks, flat keys for building locks, dimple and micro-dimple keys, lever keys, warded keys, colour keys, safe keys, cruciform keys, plastic head keys, milling blanks and accessories. With 466 products covering all standard profiles across the French and European market, this is the reference catalogue for locksmiths, key cutters and building key duplication professionals.

Keyfirst is the official distributor in France for the four manufacturers that define the European building key market: Keyline, Silca, JMA and Errebi. These four brands offer compatible and cross-referenced products, which is a decisive advantage for any workshop looking to rationalise stock: a Keyline reference corresponds to a Silca, JMA and Errebi reference. The Keyfirst catalogue includes cross-brand equivalences on every product page to simplify purchasing.

Building keys are high-volume consumables: every duplication generates a purchase. Unlike vehicle keys, which sometimes require a programming tool, flat key duplication is performed on a key cutting machine without complex electronic protocols. This is the core business of locksmiths and key cutters, and that is why the choice of supplier and blank quality directly affect duplication quality and customer satisfaction.

Standard flat key blanks: the everyday profiles for daily duplication

Standard flat key blanks form the core of the building catalogue and represent the highest volume in daily duplication. These are the standard blanks corresponding to the most widespread lock profiles in the French and European property stock. They are cut on any building key machine available on the market and cover entrance doors, landing doors, letterboxes, cellars and utility rooms.

The most common profiles in the catalogue are UN5D Keyline (compatible JMA U-5D, Silca UL050), RI18 Keyline (compatible JMA RO-29D), UN5S Keyline (compatible JMA U-5I, Silca UL051) and VC2 Keyline (compatible JMA VA-8D, Silca VAC2). These profiles correspond to locks very widely fitted on residential and commercial buildings constructed or refurbished over the past thirty years.

Standard flat blanks are sold in minimum packs of 100 units in the Keyfirst catalogue. This packaging is the professional standard for this type of product: a common blank is purchased in volume to optimise unit cost and ensure permanent availability in the workshop. The Star range (bright chrome finish) is available alongside the standard versions for workshops offering a personalisation service or working on premium lines.

Cross-brand references are a central feature of the catalogue: each product page shows equivalent references from the other manufacturers (Keyline, Silca, JMA, Errebi). This allows a workshop to switch between suppliers without stock interruptions and to mix brands according to availability without changing the cutting profile on the machine.

Dimple and micro-dimple keys: high security for quality locks

Dimple and micro-dimple keys form the second strong segment of the catalogue. They correspond to high-security cylinders fitted in premium residential buildings, professional premises, public buildings and installations requiring access rights management. These profiles are associated with the most specified cylinder brands on the market: ISEO, VACHETTE, BRICARD, FICHET, THIRARD and other premium manufacturers.

Among the most represented micro-dimple references, ISE17 Keyline (compatible Silca IE26, JMA IS10P) covers ISEO cylinders, one of the most installed brands in the French locksmith market. The THR1 Keyline reference covers THIRARD cylinders, widely found in trade and professional distribution. These micro-dimple profiles differ from flat keys through their raised points on the key head, which make unauthorised reproduction difficult without the appropriate equipment.

Why is the dimple segment strategically important for a professional? A dimple key represents a higher added-value service than a standard flat key: the end customer pays more, the margin is better, and loyalty is stronger because they return to the same workshop that knows their cylinder. It is also a segment that requires the right equipment: dimple profiles require a suitable chuck on the key cutting machine. Keyfirst supplies the compatible blanks for the main machines on the market through its key cutting machine catalogue.

For locksmiths working on high-security installations with master key plans (MUL-T-LOCK, ABLOY, MEDECO), the dimple key catalogue includes the corresponding blanks for authorised reproduction under a maintenance or access extension contract. The Keyfirst technical support team can guide you to the exact reference for a given cylinder.

Other families: from warded keys to safe keys

Warded keys cover warded locks still very common in older property stock, particularly cellar, attic and utility room locks in buildings constructed before the 1980s. This simple-to-cut profile represents recurring demand in older neighbourhoods and unrenovated residential heritage. Lever keys serve the enhanced-security locks fitted on armoured doors and mid-range safes.

Colour keys represent a commercially underexploited opportunity in many workshops. Offering a duplication in a colour key (red, blue, green, yellow) to differentiate access in a block of flats or a business is a simple service that increases average basket value without any technical complexity. A building manager with ten units will immediately appreciate the visual access management solution that a set of personalised colour keys provides.

Safe keys, cruciform keys (very common on meters, technical cabinets and utility rooms) and double bit keys complete the catalogue for specific but recurring requests in a general locksmith business. Pump keys serve pump locks widely used in car parks, communal letterboxes and industrial buildings.

Milling blanks are designed for workshops equipped with a milling machine that want to produce special profiles or reproduce out-of-catalogue keys to order. Style keys and plastic head keys allow a personalised, differentiated offer.

Keyline, Silca, JMA and Errebi: four manufacturers, one catalogue

Keyline is the reference manufacturer in the Keyfirst building catalogue. A European leader in key duplication blanks for over 50 years, Keyline manufactures its entire range in Italy to quality and dimensional tolerance standards that guarantee precise cutting on all machines available on the market. Its blanks are the reference for metal quality, finish and dimensional consistency batch after batch.

Silca, now part of the Keyline group, offers a complementary range covering specific profiles not available in the standard Keyline line. For a workshop looking to cover the maximum number of European profiles with a single supplier, the Keyline + Silca combination offers the most comprehensive market coverage. JMA, a benchmark Spanish manufacturer, and Errebi complete this offering on certain regional profiles and Iberian and southern European markets.

The strength of this multi-brand catalogue is systematic cross-referencing: for each profile, you have the equivalences between Keyline, Silca, JMA and Errebi. A key cutter can order the brand immediately available without waiting for a specific replenishment. This flexibility is particularly useful for workshops operating multiple key cutting machines from different manufacturers, each with its own gauges and cutting blades optimised for a given brand.

For a key cutting machine, blank choice is as important as operator skill. An out-of-tolerance blank produces a key that turns poorly in the lock, wears faster, and results in a dissatisfied customer. Working with recognised-brand blanks such as Keyline, Silca, JMA or Errebi is the guarantee of clean duplication and flawless service. That is what Keyfirst distributes, with competitive prices from French stock and delivery within 24 to 48 hours.

Building and vehicle keys: two trades, one distributor

Keyfirst's strength is offering under one roof the consumables for both activities of a modern locksmith or key cutter: vehicle keys (remotes, transponders, blades) and building keys (flat blanks, dimple keys, warded keys). This combined offer rationalises orders, provides a single point of contact for all supplies, and delivers both product types in a single shipment.

Professionals looking to structure and grow their building key activity also have access to Keyfirst Academy training and the Keyfirst+ programme for permanent discounts across all orders, including building blanks. Technical support is available for any compatibility questions between a blank, a lock and a key cutting machine.

To navigate the catalogue by product type, the subcategories above give access to each family. To find a reference from an original key to be duplicated, the site search engine allows direct searching by manufacturer reference (e.g. UN5D, RI18, ISE17) or by cross-brand equivalences. For any enquiry about a specific profile or non-standard quantity, the sales team is available.
