A flat can be freshly decorated and fully furnished, but a front door that will not lock properly is still a serious problem. This guide to landlord lock responsibilities explains where Scottish landlords’ duties usually begin, when a tenant may be liable, and how to deal with keys and access without creating a dispute.
Locks are not just a convenience. They protect the tenant, their belongings and the landlord’s property. A slow response to a faulty lock can also turn a manageable repair into a security risk, an insurance issue or a complaint about the condition of the home.
What are a landlord’s lock responsibilities?
In Scotland, landlords must keep a rented property in a reasonable state of repair and ensure it meets the Repairing Standard. In practical terms, external doors, locks, windows and other security features need to work as intended. A tenant should be able to secure their home properly from the outside and feel safe inside it.
That does not mean every lock must be replaced at the first sign of wear. A lock that is stiff but still secure may need cleaning, adjustment or a small repair. A key that only turns with force, a handle that drops, a door that will not engage with the frame, or a cylinder that is damaged should be dealt with promptly. On uPVC and composite doors, the problem is often alignment rather than the lock itself. Ignoring it can strain the gearbox and leave the door unable to lock at all.
The responsibility usually sits with the landlord where the fault results from age, ordinary use, poor fitting or a problem with the door. It is sensible to arrange a proper assessment rather than asking a tenant to keep forcing a key or lifting a handle harder each day.
When the repair is urgent
A door that cannot be locked, has been forced, or leaves the property exposed is an urgent security repair. The same applies if a tenant is locked out because a supplied lock or key has failed.
In these cases, the priority is to secure the property and restore safe access. A good locksmith will try non-destructive entry first where possible, then explain the repair options and price before work starts. Keep invoices and photographs of damage, particularly after an attempted break-in, as they may help with an insurance claim.
A failed lock is not always an emergency. If the door remains secure and the tenant has another safe way to enter, the repair can normally be booked as soon as reasonably practical. Clear communication matters. Tell the tenant what will happen, who is attending and when they can expect an update.
Keys, spare keys and tenant privacy
A landlord should provide the keys needed for the tenant to access and secure the property at the start of the tenancy. That normally includes keys or fobs for the main entrance, any communal access, bins or secure parking where these form part of the let.
Keeping a spare key is sensible for emergencies, but it is not permission to enter whenever it is convenient. Tenants have a right to quiet enjoyment of their home. Except in a genuine emergency, such as a fire, serious leak or immediate risk to the building, a landlord should give proper notice and arrange access at a reasonable time. For most rented homes in Scotland, at least 48 hours’ written notice is the normal expectation unless the tenant agrees otherwise.
Be clear about who holds spare keys. If a letting agent, contractor or cleaner has one, keep a simple record and make sure keys are returned when their work ends. A key box left outside a property may appear convenient, but it can undermine security if the code is widely shared or not changed between occupancies.
Lost keys and lockouts
If a tenant loses their own key, leaves it inside or needs help after a personal lockout, they will usually be expected to meet the cost. The position can change where the supplied key was worn, snapped through no fault of the tenant, or the lock was already faulty.
Avoid making assumptions before charging anyone. Ask what happened, inspect the lock if necessary, and keep the decision proportionate. Replacing an entire multi-point lock after a simple lost key may be unnecessary. In some situations, a new cylinder and a fresh set of keys are enough.
Can a tenant change the locks?
Tenants sometimes want to change a lock after a relationship breakdown, a concern about old keyholders, or a previous occupier still having access. That concern can be legitimate, but tenants should check their tenancy agreement and speak to the landlord or agent first where possible.
A blanket refusal is rarely helpful if there is a genuine safety concern. Equally, a tenant should not alter the door, fit unsuitable hardware or leave the landlord without a means of emergency access. A practical agreement is often best: fit a compatible replacement lock, provide a key or agree an emergency access arrangement, and keep the original lock to be refitted when the tenancy ends if required.
For communal doors and master-key systems, changing a cylinder without checking compatibility can affect other residents or compromise the building’s access control. This is one situation where professional advice can prevent an expensive mistake.
Changing locks between tenancies
Scottish landlords are not generally required to replace every lock automatically whenever a tenant moves out. However, a lock change or rekey is often the sensible choice when key control is uncertain. Former tenants may have made copies, keys may have been handed to tradespeople, or a key may never have been returned.
At minimum, inspect all external doors between tenancies. Check that keys operate smoothly, handles lift correctly, letterboxes are secure, and the door closes tightly into the frame. This is also a good time to identify worn cylinders, loose handles and misaligned uPVC or composite doors before a new tenant moves in.
For a property with a history of lost keys, a change of cylinder provides reassurance at a relatively modest cost compared with the consequences of unauthorised access. It also gives the landlord a clean record of how many keys were issued at the start of the new tenancy.

Damage, break-ins and who pays
Landlords are normally responsible for repairing damage caused by an attempted burglary or forced entry, including the lock, door hardware and any necessary boarding or securing work. The tenant should report the incident promptly and contact the police where appropriate.
The position is different where damage clearly results from a tenant’s misuse or negligence. Examples might include forcing the wrong key, damaging a lock after being warned about a fault, or losing keys alongside information that identifies the address. Even then, costs should be fair, evidenced and discussed rather than simply deducted without explanation.
A detailed inventory helps. Photograph the locks, doors and key sets at check-in, record how many keys were issued, and note existing wear. At check-out, document missing keys or new damage. These simple records reduce arguments and make any deposit discussion much clearer.
Extra considerations for HMOs and holiday lets
HMO landlords have additional safety duties, and local authority licence conditions can be more specific than the general rules for a single rented home. Bedroom-door locks, escape routes and communal entrance security must work together. A lock that makes a room feel secure but prevents a quick escape in a fire is not a suitable solution.
Before fitting locks to bedroom doors or altering shared entrances, check the relevant HMO licence conditions and fire safety requirements for the local authority area. Do not assume a lock type that suits a standard flat will suit a shared property.
Holiday-let and short-let hosts face a similar key-control challenge, only more often. Codes for key safes and smart locks should be changed regularly, physical keys should be accounted for after every stay, and any door fault should be fixed before the next guest arrives. Guests who cannot secure a property are unlikely to view it as a minor inconvenience.
A practical approach that protects everyone
The best landlord lock policy is straightforward: provide secure, working locks; respond quickly when security is affected; respect the tenant’s privacy; and keep written records of keys, reports and repairs. Tell tenants how to report an urgent lock problem and who to contact outside normal hours, so they are not left guessing when a door will not secure.
Where there is doubt about whether a lock needs repair, adjustment or replacement, arrange an inspection from an insured, Disclosure Scotland checked locksmith who can give clear advice without pressure. Scotia Locksmiths can assess faulty locks, door alignment and security upgrades across central Scotland, with upfront pricing before travel and no call-out fee.
A well-managed lock is a small part of a tenancy, but it sends a clear message: the property is cared for, the tenant’s safety is taken seriously, and problems will be dealt with properly.
