What high security locks cost in Coventry
High security work is priced from our Coventry lock change figures, 38 recorded jobs, all inc VAT, with the typical figure in the middle of the range. A single anti-snap euro cylinder upgrade is toward the lower end and is the best value improvement for most doors; a full set across every external door, or a BS3621 five-lever mortice deadlock on a timber door, costs more. We price the specific upgrade before we start, and there is no call-out fee when we do the work.
The upgrades that actually help in Coventry
Not every "security" product is worth the money, so we focus on the ones that change the outcome against real attacks. An anti-snap euro cylinder is the priority for uPVC and composite doors, because it removes the single most exploited weakness. A BS3621 mortice deadlock is the standard for timber final-exit doors and is what most insurers expect. Beyond the cylinder itself, we can add security handles that shield the lock, and reinforce strike plates so the door resists being forced open. For business premises or landlords, restricted-key and master-key systems stop keys being copied without authorisation.
Honest advice, not a sales pitch
Because lock changes are the minority of what we do in Coventry, we are not in the habit of pushing new locks on doors that do not need them. If your existing lock already meets a good standard, we will tell you and save you the money. If it is a snap-vulnerable cylinder on a family front door, we will explain exactly why an upgrade is worth it. A high security lock also pairs naturally with a full lock replacement after a move, and it is the standard fix we fit as part of burglary repair once a door has already been forced.
How the job goes in Coventry
We are based in the CV6 area and cover the CV1 to CV8 districts and the CV belt. On arrival we check what you currently have, measure the cylinder or lock case, and fit the correct-size high security replacement so it sits flush and cannot be gripped or levered. We test it and hand over the full set of keys.
For more, the national high security locks page covers standards across all areas, and our honest look at whether high security locks are worth it is a good read. It links back to the Coventry hub.
