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, this deadlock is specifically designed for external doors. It is BS3621:2007 compliant, which means it is insurance and police approved, meeting the security requirements typically requested by home insurance providers.

The Asec Five Lever Deadlock features several security enhancements to deter intruders, including:

  • A high-security 5-lever mechanism.
  • Anti-drill plates on both the cap and the case to resist drilling attacks.
  • A robust steel case construction.

This lock is available in two case sizes: 64mm and 76mm. You should measure the depth of the existing hole in your door or the distance from the edge of the door to the center of the keyhole to determine which size is the best fit for your installation.

Each Asec deadlock comes with the following components to complete your installation:

  • The 5-lever deadlock unit.
  • Two keys.
  • Matching escutcheons (keyhole covers).
  • A 10-year manufacturer's guarantee for peace of mind.

The Asec 5 Lever Lock Extra Key service provides additional, precision-cut keys specifically designed for Asec 5 lever mortice locks. These keys are engineered to interact correctly with the internal lever mechanism of both sashlocks and deadlocks, ensuring a smooth rotation and reliable bolt throw without the friction or sticking often found with lower-quality duplicates.

Using correctly specified extra keys is essential for maintaining the operational life of the door hardware. These keys are cut to the precise depths required by Asec mechanisms, preventing the mechanical failures that can occur when using poorly matched aftermarket blanks.

The Firestop Intumescent Kit is a critical safety accessory designed specifically for use with Asec 5 Lever BS Deadlocks. When a door is morticed to accommodate a lock, the fire resistance of the timber is naturally reduced. This kit provides a high-performance intumescent gasket that wraps around the lock case and forend to restore the door's fire-rated integrity.

The material is engineered to react to heat, expanding at high temperatures to fill the voids around the lock hardware. This action effectively blocks the path of flames and prevents heat transfer through the door leaf. It is an essential component for ensuring that fire-rated timber doors maintain their certification when fitted with ironmongery.

Typical applications include commercial buildings, HMOs, and residential fire doors where British Standard deadlocks are installed. The kit is designed for straightforward application, either during the initial installation of the lock or as a retrospective upgrade to meet updated fire safety requirements. It provides a reliable seal that has been tested for use on 30-minute (FD30) and 60-minute (FD60) timber fire door sets.
