Moving into a rented flat in Manchester and wondering who else has a key? It is a fair question — and the honest answer is that nobody really knows. So, can tenants change the locks? In most cases you can, but only with your landlord's agreement, and there are a few conditions that protect both of you. Get it wrong and you risk a breach of your tenancy agreement or a deduction from your deposit. Get it right and it costs less than a weekly shop.

This guide covers what your tenancy agreement almost certainly says, the narrow situations where you can act without permission, what your landlord is and is not allowed to do, and how to change a lock without leaving a mark on your deposit.

This is general guidance from working locksmiths, not legal advice. For a dispute, speak to Shelter, Citizens Advice or a housing solicitor.

Why so many renters ask this question

Manchester is the most rented city in the country. Around 62 per cent of households here rent rather than own, with roughly a third of all households in the private rented sector — well above the England average. That means an enormous number of front doors change hands every year, most of them in August and September as tenancies turn over.

Here is the part that worries people, and rightly so. When a tenancy ends, the outgoing tenant hands back the keys they were given. Nobody can account for the ones they had cut at a kiosk for a partner, a housemate, a dog walker or a mate who was staying for a fortnight. Unless the landlord changes the lock between lets, those keys still open your door.

We see this most in the student belt around Withington and Fallowfield, where houses turn over annually and key sets multiply, but it is just as true of a converted flat in Chorlton or a new-build apartment in Salford with a shared entrance fob.

What your tenancy agreement almost certainly says

Nearly every assured shorthold tenancy agreement in England contains a clause requiring the landlord's written consent before you alter the property. Changing a lock counts as an alteration.

Changing the locks without asking is therefore usually a breach of contract. In practice that rarely ends in eviction over a single cylinder swap, but it is grounds for a Section 8 notice, and it gives a landlord a straightforward reason to withhold part of your deposit at the end of the tenancy. It is not a fight worth having when a short email will usually get you a yes.

The reason for the clause is not landlords being controlling. They have statutory duties that require access: annual gas safety checks, electrical safety inspections, and repairs under Section 11 of the Landlord and Tenant Act 1985. If a pipe bursts in the flat above yours at two in the morning and nobody can get in, the damage bill climbs quickly.

How to ask, and how to get a yes

Put it in writing — email is fine, and it gives you a record. Keep it short and practical:

Say what you want changed and why. "The previous tenants may still have keys" is a reason most landlords accept without argument.
Confirm you will use a qualified locksmith, not a DIY attempt.
Confirm you will provide a new key straight away.
Confirm you will keep the original lock and refit it at the end of the tenancy.
Offer to send the invoice, in case they want to cover the cost.

That last point is worth making. A lock change between tenancies is good practice for the landlord too, and plenty will pay for it rather than have you do it. It protects them from a claim if a former tenant lets themselves back in.

When you can change the locks without permission

There are narrow circumstances where a tenant is justified in acting first and explaining afterwards.

You are at risk from someone who has a key. If you are fleeing domestic abuse, or an ex-partner or former housemate has keys and will not return them, your safety comes before a contractual clause. This is the clearest exception, and no reasonable landlord or judge would expect you to wait for an email reply. If you are in this position, Manchester's domestic abuse services and the police can support a request, and you may not have to provide the landlord with a key at all — take advice from Shelter or a housing solicitor on that point specifically.

There has been a burglary or an attempted break-in. If your door has been forced, the lock is compromised and the property is not secure. Making it safe is urgent, and you should tell your landlord the same day. Our burglary repairs work almost always starts this way: secure the property first, paperwork second.

The lock has failed. If a key snaps in the cylinder or a mechanism seizes and you cannot lock the door, that is a repair, not an alteration. Report it to the landlord or agent immediately, and if they cannot get someone out and the property is left insecure, arranging an emergency lockout and repair yourself is reasonable. Keep the invoice — you may be able to reclaim the cost.

Your landlord repeatedly enters without notice. Your landlord must give at least 24 hours' written notice and visit at a reasonable hour, except in a genuine emergency. Persistent entry without notice interferes with your right to quiet enjoyment. Even here, write to them first and keep the correspondence; it will matter far more than the lock change if it ever goes further.

In every one of these cases, document what happened, tell your landlord in writing as soon as you reasonably can, and keep the original lock.

What your landlord cannot do

This runs both ways, and renters are often unaware of how strong their position is.

Your landlord cannot change the locks to keep you out. Doing so while you are still lawfully a tenant is unlawful eviction under the Protection from Eviction Act 1977 — a criminal offence, not merely a civil dispute. It does not matter if you are behind on rent, and it does not matter if they have served notice. Ending a tenancy requires a court order and, ultimately, county court bailiffs.

If a landlord changes a lock for a legitimate reason, such as a repair after a break-in, they must give you a working key straight away. If you have been locked out and cannot get a key, contact the council's housing options team or the police, and get advice from Shelter's emergency helpline. We are sometimes called to let tenants back into their own homes in these situations, and we ask for proof of your right to be there before we open anything.

Doing it properly: the practical bit

If you have permission, the job itself is usually straightforward.

On a uPVC or composite door, only the euro cylinder needs changing — the barrel the key goes into. The multipoint mechanism inside the door stays put. Swapping the cylinder takes about ten minutes and leaves no trace. Fit a TS007 3-star or Sold Secure Diamond anti-snap cylinder while you are at it; it costs a few pounds more and defeats lock snapping, still the most common way doors are forced in Greater Manchester. Our euro cylinder guide explains the measuring and the ratings in detail.

On a wooden door, you likely have a mortice lock in the door edge and possibly a night latch on the face. A like-for-like mortice replacement is fine; anything that needs the mortice pocket enlarging is an alteration you should not make in a rented property without explicit written consent. The Victorian and Edwardian doors common in Didsbury and the terraces around Chorlton are exactly where this matters — they are often original, and cutting into one is not something you can undo.

On a flat with a communal entrance, you can change your own front door lock but not the building's. Communal doors, fobs and intercoms belong to the freeholder or management company. In city centre blocks, ask the building manager to deactivate any fob the previous tenant did not return — that is usually free and takes minutes.

Costs to expect

For a uPVC or composite door, expect roughly £90 to £160 to have a locksmith supply and fit a euro cylinder, with anti-snap cylinders at the upper end. A British Standard BS3621 mortice lock on a wooden door is typically a little more, reflecting the extra fitting time.

Beware the national call-centre outfits that advertise a low headline figure and then add a call-out fee of £40 to £90 on arrival. An independent local locksmith should quote you one fixed price on the phone. Our Manchester locksmith cost guide breaks down what moves the price, and BS3621 explained covers why the standard matters for your contents insurance.

Protecting your deposit

Three rules, and you will never lose a penny over this:

Keep the original lock. Bag it, label it, put it in the bottom of a wardrobe. Do not let a locksmith take it away.
Do not modify the door. Same lock size, same fixing holes, no new drilling.
Refit the original before you hand the keys back, or agree in writing with the landlord that the new one stays.

Deposit deductions for lock changes almost always come down to a tenant who could not produce the original lock. Keep it and there is nothing to argue about.

When to call a locksmith

Call a professional if you cannot get a key to turn, if the door will not lock at all, if a key has snapped off in the cylinder, or if the door has been forced. Call one for a straightforward swap too — a fitted cylinder from a locksmith costs little more than a decent one bought online, and it removes any argument about workmanship if the landlord queries it later.

The short version

You can usually change the locks in a rented home, but you should ask first, provide a key, keep the original lock and put it back at the end. The exceptions are safety-related and genuine: abuse, burglary, a failed lock, or a landlord who will not respect your right to quiet enjoyment. And a landlord can never lawfully change the locks to shut you out.
