Landlord & Tenant Lock Changes

A landlord's legal duty of care includes taking reasonable steps to keep a property secure between occupancies. Most standard tenancy agreements require the landlord to ensure the property is secure at the start of each new let, yet lock changes at the handover stage are still one of the most commonly skipped tasks. The reason is usually timing: the previous tenant vacates on a Saturday evening, the new tenant moves in on the Sunday, and there is no obvious moment to fit a new cylinder. That gap is precisely when a 24 hour locksmith London service makes the most practical difference — we are available to attend at short notice, any day of the week, so the handover can happen on the schedule that suits the parties involved rather than a locksmith's office hours.

Letting agents managing properties in Bermondsey — particularly around the busy rental corridors of Tower Bridge Road, Abbey Street and the streets running south from Borough — often coordinate multiple move-outs in a single month. For those agents, having a reliable door lock replacement London team on call means handovers stay on time without compromising security. We work alongside property managers and housing associations as well as individual landlords, and we can confirm the work and issue a written record of the new lock fitted so it can be filed alongside the inventory and the new tenancy agreement.

The specific work involved in a tenancy lock change depends on the type of door and the locks already fitted. Most Bermondsey properties have one of three common configurations: a traditional timber front door with a Yale-type nightlatch and a 5-lever mortice deadlock (the combination most home insurers require, often to BS3621 standard); a uPVC or composite door fitted with a multipoint lock operated by a euro cylinder; or a communal entrance with a separate flat front door behind it, each of which may need attention. Our technicians carry a range of cylinders and lock hardware to appointments, so in the majority of cases the new lock can be fitted in a single visit without ordering parts.

Euro cylinders on uPVC and composite doors carry an additional security concern worth flagging at every tenancy change: cylinder snapping. Snap attacks — where a burglar breaks the exposed part of the cylinder to manipulate the cam inside — remain a known method of forced entry in London. When we carry out a lock change on a uPVC door, we always recommend fitting an anti-snap, anti-pick, anti-drill cylinder that meets the TS007 3-star rating. This is not an upsell; it is the standard our technicians apply to their own family homes. We also carry out uPVC door lock repair London properties may need if the multipoint mechanism is not engaging correctly, as a stiff or misaligned mechanism is often what gets reported as a lock failure during a stressful move-out.

Because we are a mobile locksmith service, every job begins with a phone call to 020 7871 2569. We will ask you about the type of door, the number of locks, your postcode district, and the time you need us. From that information we can confirm an exact quote before anyone travels to the property — there are no hidden additions once we arrive. The factors that determine the final figure are straightforward: the type of lock or cylinder being replaced, how many locks are involved, the time of day (evening, weekend and bank holiday visits reflect the hours), the travel distance from our current location, and whether any specialist parts are required that are not on the van. We do not use vague price ranges; you receive a specific figure and you decide whether to proceed.

We also carry out damage-free work wherever the situation allows. Landlords are understandably concerned about avoiding repair costs to door frames or furniture, and our technicians are trained to remove and replace locks without causing unnecessary damage to paintwork, frames or the door itself. If a lock cannot be changed without some remedial work — for instance because a previous tenant has damaged a mortice housing — we will explain that clearly before starting. For letting agents who need a paper trail, we can provide a brief written record of the lock type fitted and the number of keys handed over, which sits neatly alongside a check-in report.

If you are arranging a tenancy handover and need a locksmith London team available at a specific time, call us on 020 7871 2569 — we answer 24 hours a day and can often accommodate same-day or next-morning appointments even during busy letting periods.

Tenants often assume that because a landlord has handed over a fresh set of keys, the previous occupant's keys have been accounted for. In practice, that is rarely something a tenant can verify independently. If you are moving into a flat on Bermondsey's Long Lane, a studio near Leathermarket Street, or a house share off Old Kent Road, it is entirely reasonable — and in some cases your tenancy agreement may allow it — to request confirmation that the locks have been changed before your move-in date. If that confirmation is not forthcoming, some tenants choose to arrange a lock change themselves and present the receipt to the landlord; whether the landlord reimburses that cost depends on the tenancy terms, so it is worth checking first.

What tenants should not do is attempt to change locks without speaking to the landlord or letting agent. Most tenancy agreements require written permission before a tenant alters a lock, and fitting a lock the landlord cannot access may be a breach of those terms. The practical solution is to agree the lock change as part of the move-in process, have it carried out by a professional, and ensure the landlord receives a copy of any new keys — usually required under the agreement. Our technicians are used to navigating this dynamic sensitively and can liaise with both parties to ensure the right number of key copies are handed over at the right time.

Not every lock change happens on a planned schedule. A tenant may lose the only key on the day of moving in. A landlord may need a lock changed urgently after a tenancy dispute. A letting agent may receive a call on a Sunday evening from a new tenant standing outside a Bermondsey property with nowhere to go. These are genuine locked out London situations, and they are exactly what our 24/7 service is set up to handle. We send a technician straight away and are usually on site within about 30 minutes, day or night.

When we attend an emergency lock change, we follow a straightforward verification process: we ask to see proof of identity and, where relevant, proof of a right to access the property — such as a tenancy agreement, a landlord's authority, or a letting agent instruction. This protects everyone involved and is standard practice for any professional mobile locksmith. Once access and authority are confirmed, we carry out the lock change as efficiently as possible, issue the new keys, and leave the property secure. Our technicians carry insurance for the work they carry out, and they are experienced in working calmly under the time pressure that emergency situations naturally bring.
