FAQs

All the extra keys for the locks are cut to the specific locks that have been ordered.

There are 2 different sizes of lock cases as each lock will give you a different backset. This is the distance from the edge of the lock to the keyhole / spindle for handles. The bigger locks are better for solid wooden doors as they move the keyhole away from the door stop further. If you have a large door stop and fit a 64mm lock case you can find that you hit your knuckles on the door stop when you turn the key. Alternatively the 64mm lock case is better when you have a glass panelled door as you may not have enough wood on the stile to fit the 76mm lock into before you hit and therefore smash the glass. This is very important to check when installing locks to doors with glass in.

No, if the door is a communal entrance/ exit you MUST have a turn on the inside, so a 5 lever key on the inside is not suitable.

There are specific locks we sell called Egress locks that meet both the Insurance and Fire regulations so these are suitable for communal entrance doors.

To meet the fire regulations you need to be able to exit a communal door without the use of a key. If you are using the lock on your personal front door then they are fine but if others use the door you need to look into getting a turn knob internally so you can exit without the use of a key.

With outward opening doors you can not get a BS3621 outward opening nightlatch (see our section for all the options we have available) but if you install a standard security nightlatch you can also fit a BS3621 deadlock to the door which will give you the insurance rated lock required. As the deadlocks are not handed you can use them on any type of wooden door.

With most locks that are altered to make them keyed alike you will only get 1 x set of keys with them. So if the locks normally come with 2 you will only get 2 keys total and if they come with 3 keys you will only get 3 x keys total when ordered keyed alike.

Yes you can, we would need a key back as we dont hold any records of your keys but this is possible. Please get in touch first so we can confirm everything is ok to do and then you can post your key back to us (taped to a piece of card...essential!!)

Yes, this is possible but it is important to make sure you select the same brand and model. The internals and the keys need to match so we can key the locks alike.

We do try to list the products together in our series tab on the product page which should show the suitable products that can be keyed alike together.

If in doubt please ask us and we will let you know.

A rebate set is only required on double rebated doors. If you only have a single door then you will receive all the parts you require with the lock. If you need a rebate set you will need to check the size of your rebate. The most common is 13mm but on older doors they can be 19mm or 25mm.

With the 5 lever locks they are designed to be high security so there are thousands of different keys so the keys do not come with numbers on. Therefore we can not cut additional keys for these locks without a key to copy from. If you post it back to us we can do it for you (please contact us first before you send it) or alternatively nearly all the keys we sell are available from local locksmiths in your area. They maybe more expensive so we would recommend buying the extra keys at the time of purchase so we can cut and try them before we ship the order.

Deadlocks are suitable for either hand and inward and outward opening doors. The locks have keyholes either side and can be used on the left or right hand side of the door.

Yes, the ERA Viscount 5-lever deadlock is an ideal entry-level security upgrade. It is specifically designed to replace existing 2 or 3-lever mortice locks, providing a higher level of protection for your property.

Every ERA Viscount Deadlock is supplied with the necessary components for a standard installation, including:

  • Two keys
  • Matching polished brass escutcheons
  • Silver finish lock case

This lock is available in two standard case sizes: 64mm and 74mm. When selecting your lock, ensure you choose the size that best fits your door's existing cut-out or desired backset depth.

Yes, while this specific model is a standard deadlock, the ERA Viscount range includes a rebated version. This makes it suitable for use on rebated French doors where the doors overlap.

The ERA Rebate Set is a technical accessory specifically designed to facilitate the installation of an ERA Viscount Deadlock into a pair of rebated double doors. In situations where the meeting stiles of two doors overlap, a standard flat strike plate is insufficient; this rebate set provides the necessary stepped profile to ensure the deadlock bolt engages securely and correctly within the frame.

This component is essential for timber door applications where a rebate has been cut into the door edge. It is frequently used for external front or rear double doors and high-security internal pairs. The set is suitable for new joinery projects or as a replacement part for existing ERA installations where the rebate hardware requires upgrading or renewal.

  • Designed for use with timber door frames and doors
  • Ensures mechanical alignment between the lock body and strike
  • Bridges the gap on rebated meeting stiles for a secure closure

The ERA Intumescent Kit is a specialist fire safety accessory designed to be used in conjunction with the ERA Fortress BS Deadlock range. This kit is essential when installing these mortice locks into fire-rated timber doors, providing the necessary protection to maintain the door's integrity during a fire.

Manufactured from high-performance intumescent material, the kit is designed to expand rapidly when exposed to heat. This expansion seals the voids created by the lock mortice, preventing the spread of flames and hot gases through the door assembly. Using a pre-cut kit ensures that the lock is fully protected without the need for manual cutting or shaping on-site, which improves installation speed and accuracy.

The kit is typically used in both new builds and refurbishment projects where fire safety standards must be met. It is compatible with 30-minute and 60-minute fire doors, depending on the door manufacturer's specific testing and certification. By isolating the metal hardware from the timber, it significantly reduces the risk of the door charring and failing prematurely at the lock position.
