Landlord & Tenant Lock Changes

Yes — a landlord or letting agent may change the locks after an outgoing tenant has formally vacated and returned all keys. This is standard practice and a sensible security step. What is not permitted under UK law is changing the locks on a property while it is still occupied by a tenant, or doing so to prevent an occupant from returning. We confirm proper consent at every job, so if you are a landlord or letting agent booking a between-tenancy lock change, we simply ask you to confirm that the previous occupant has vacated and keys have been surrendered.

Many insurers and some letting agents in the Dagenham area specify a BS3621 5-lever mortice deadlock on timber doors and, for uPVC or composite doors, a euro cylinder that meets at least the TS007 1-star standard — with TS007 3-star anti-snap cylinders increasingly recommended. If you are unsure what your insurer requires, check your landlord policy documents before we arrive and we can confirm on site whether the hardware we carry meets that specification. Upgrading to a 3-star anti-snap cylinder at a tenancy change is a practical step that reduces the risk of cylinder-snap attacks, which are a known concern in the Greater London area.

We do not advertise fixed price packages because the right quote depends on several factors: the type of lock or cylinder being replaced, the number of doors covered in the visit, the grade of replacement hardware, the time of day, and the postcode district within our service area. When you call 020 4511 6133, we will ask a few questions about the property and confirm an exact price before anyone travels out. There are no additional charges added once we arrive. We believe clear up-front pricing is more useful to landlords and tenants than headline figures that may not reflect the actual job.

A tenant is generally not permitted to change the locks without the landlord's written consent, as most tenancy agreements specifically prohibit it. If a tenant has a genuine safety concern — for example, believing an ex-partner still holds a key — the right approach is to contact the landlord or letting agent immediately and request an agreed lock change. In urgent situations where safety is at risk, speaking to the police or a housing charity for guidance is advisable. Where the landlord agrees to a lock change, we can attend the property and complete it promptly, with a new set of keys made available to both parties as agreed.

This is not uncommon, particularly after longer tenancies. If the existing cylinder or mortice case is seized, damaged, or has been tampered with, our technician will assess the door and use the least invasive method available to remove or bypass the existing hardware before fitting the replacement. In most cases we can carry out a full lock change without causing damage to the door or frame. Where the door itself has been forced or the frame damaged during the tenancy, we will advise on what remedial work is needed alongside the new lock fitting. If you discover this situation on a checkout day, call 020 4511 6133 — we operate as an emergency locksmith Dagenham service and can attend the same day, including evenings and weekends.

We send a technician straight away and are usually on site within around 30 minutes of your call, though arrival times can vary depending on traffic and demand at the time. We cover all parts of Dagenham, including postcodes RM8, RM9 and RM10, and operate 24 hours a day, seven days a week, including bank holidays. For planned tenancy handovers, you are welcome to book in advance for a specific day and time window, which many landlords and letting agents prefer. For urgent or same-day needs, calling 020 4511 6133 is the fastest way to get a technician on the way.
