Landlord & Tenant Lock Changes

A tenancy changeover is one of those moments when it is tempting to focus on the inventory, the deposit, and the cleaning — and overlook the locks entirely. The reality is that a key could have been given to a family member, a friend helping with a move, or a tradesperson during the previous tenancy, and none of those people are under any obligation to return it. The outgoing tenant may be perfectly trustworthy, but the people they gave keys to are unknown quantities. For a landlord or letting agent, leaving the original lock in place between tenancies is an avoidable risk. For an incoming tenant, it is entirely reasonable to want confirmation that the locks have been changed before you move your belongings in.

Many insurers now require that front doors are fitted with locks meeting BS3621 — typically a 5-lever mortice deadlock alongside a Yale-type nightlatch, or on uPVC and composite doors a high-security euro cylinder. If the existing lock is worn, outdated, or simply not up to that standard, a tenancy changeover is the ideal moment to upgrade at the same time. Our technicians will check what is fitted, explain what the options are, and carry out any work with minimal disruption to the door — damage-free where the door and frame allow.

The term 'lock change' covers several distinct jobs depending on the type of door. On a traditional timber front door you are most likely looking at replacing the euro cylinder in the Yale nightlatch and either replacing or re-keying the 5-lever mortice deadlock body. On a uPVC or composite door — which is common on many Sidcup properties built from the 1990s onwards — the door will have a multipoint locking mechanism and a euro cylinder. Replacing the euro cylinder on these doors is a straightforward job, but it is worth knowing that standard euro cylinders carry a snap risk: a thief can snap the exposed portion of the cylinder and gain entry in seconds. We carry anti-snap, TS007 3-star rated cylinders that eliminate this vulnerability, and we always recommend them for uPVC and composite doors.

For flats — whether in a purpose-built block or a converted house — there is typically the flat's own front door to consider as well as access to the communal entrance. We can work on both. For landlords managing multiple units in one block, we can coordinate visits to minimise disruption. If you are a letting agent handling an end-of-tenancy in a hurry because a new tenant is moving in the following day, call us on 020 3757 5665 and we will send a technician straight away — we are usually on site within around 30 minutes of your call.

Every job is different, and the price of a door lock replacement in Sidcup depends on a number of specific factors rather than a fixed tariff. The type of lock being replaced makes a significant difference — a euro cylinder swap is a different scope of work from replacing a full multipoint mechanism or a 5-lever mortice case. The time of day matters too: calls in the early hours of the morning on weekdays, or on weekends and bank holidays, reflect the out-of-hours nature of the work. Travel distance from our base and the parts required for your specific door all feed into the final figure as well. What we commit to is this: we confirm an exact price on the phone before we set off, and that is the price you pay. We never carry out unnecessary work — if the existing lock is in good condition and simply needs a cylinder swap rather than a full replacement, that is what we will tell you.

We work with landlords and letting agents who need a quick turnaround quote so they can factor the cost into an end-of-tenancy process or a maintenance budget. We also work with individual tenants who have just collected the keys to a new flat on, say, Station Road or one of the residential streets off the A211 and want the peace of mind of knowing they are the only keyholder. Whatever your situation, the conversation starts with a phone call to 020 3757 5665, available any time of day or night.

Landlords have a legal and practical interest in ensuring a property is secure between tenancies. Fitting a new cylinder or replacing the lock entirely at changeover means you can account for every key set issued from day one of the new tenancy. It also demonstrates to incoming tenants that you take the security of their home seriously — which is not a small thing when you are trying to retain good tenants in a competitive rental market like Sidcup. If you manage several properties across the DA14 and DA15 postcode districts, we can work with you to build a consistent schedule around tenancy end dates.

Letting agents often find themselves under pressure at changeover — there is a gap of hours or a single day between the outgoing tenant leaving and the incoming one arriving, and a great deal has to happen in that window. A lock change does not need to be the item that holds everything up. Our mobile service means a trained technician comes to the property at a time that fits your schedule, including evenings and weekends. Incoming tenants should feel equally empowered to request a lock change — even if the landlord has assured you the locks are fine, it is a reasonable condition to raise before or shortly after moving in, and it is a service you can arrange directly with us if your landlord is happy for you to do so. For any party involved, we are available around the clock on 020 3757 5665.
