Locks and Door Safety for Seniors: Keys, Chains and Entry

The two needs: security and access

Security needs: - Keep out burglars, distraction thieves and fake officials. - Give the person control over who enters. - Allow safe checking of visitors.

Access needs: - Allow the person to leave quickly in a fire. - Allow family, carers and neighbours to enter when invited. - Allow responders to enter in an emergency when the person cannot open the door. - Allow the person to get in themselves, without struggling with keys.

A good door plan meets all four.

The basics: a sound door and lock

• Door and frame. A solid door, with a frame in good repair, is the foundation. Weak frames, thin wood and loose hinges are easy to force. A security grille or a second door outside can add protection, but must be openable from inside quickly, and must never trap a person in a fire.
• Main lock. A good quality lock, correctly fitted. Many Indian homes use mortice locks, rim latches or multi-point locks. Choose a lock that the person can operate easily; see below for ease-of-use.
• Hinges and strike plate. Fixed with long screws into the frame.
• Latch. A lock that automatically engages when the door is closed prevents accidentally leaving it unlocked, but may lock out the person if they forget a key. Weigh this.
• Peephole or door viewer, at a suitable height for the person, ideally a wide-angle type. For a wheelchair user, mount at seated eye level.
• Door chain or restrictor, which allows the door to open a few centimetres so the person can see and speak to a visitor without letting them in. Fit with long screws. Chains give limited protection, but help; ensure it can be released from inside by weak hands. Avoid chains that cannot be disengaged by responders if the person has fallen with the chain on; see below.
• Intercom or video doorbell: lets the person see and speak to a visitor, and, if linked to a phone, lets a family member do so too; consider privacy for visitors and neighbours; see privacy and dignity with monitoring.
• Good lighting outside the door, with a motion-sensor light.
• A clear threshold so the person can reach the door safely; see stairs, steps and thresholds.

Making locks easy for older hands

Arthritic fingers, tremor, weak grip and poor eyesight make some locks hard.

• Lever handles rather than round knobs; see arthritis daily living gadgets.
• Key turners: a large grip that fits over the key and gives leverage.
• Large, easy-to-grip keys, coloured or tagged, and a key hook at a fixed place near the door.
• Thumb-turn locks on the inside, so no key is needed to exit (but see warnings below about keyed locks on the inside).
• Digital locks with keypad, card or phone; no key needed. Check that the keypad is large and clear, and that the person can remember and enter a code; for people with dementia, codes may be forgotten.
• Doorbell and door alarms that suit hearing needs; see hearing loss home care guide.
• Door closers can make the door heavy; adjust to a gentle setting.
• Light and contrast around the lock so it is easy to see.

Keys: spare keys and how to manage them

• Do not hide a spare key under the mat, in a flowerpot, on the door frame or in the meter box. Burglars know these spots.
• Give a spare key to a trusted person nearby, who can come quickly: a neighbour, a relative or a friend. Make sure they are reachable day and night.
• Use a key safe, a coded box on the wall; see key safe guide.
• A key with building security can work, with a log of who takes it and when; see safety in gated societies and apartments.
• Keep a record of who holds keys and codes, and change locks or codes if a key is lost, a carer leaves, or a relationship ends.
• Do not label keys with the address.
• Keep keys in a regular place, away from the door where they can be seen through a letterbox.
• Do not leave the key in the inside of a lock that can be reached from outside through a window or glass panel.

Internal bolts and locks: a safety trap

Many older people bolt the door from inside at night, which feels secure. But a bolt, a second lock or a chain that is fastened means that nobody can enter from outside without breaking the door. If the person falls, becomes ill or is unconscious, rescuers are delayed.

Think about:

• Use a bolt only when someone else is in the house, or when the person is able to respond.
• Choose a lock that can be opened from outside in an emergency, such as certain thumb-turn locks with an emergency release, or a lock that can be opened by a key from outside even when the thumb-turn is engaged. Ask a locksmith.
• Avoid keyed locks on the inside that need a key to exit: in a fire, a person may not find the key. If keyed locks are used, keep the key in a fixed, visible place near the door.
• Agree on a plan for emergency entry: a key safe, a neighbour with a key, security staff or a door that can be forced with minimal damage; see how an emergency alert system works.
• Tell responders: an emergency card on the fridge or the door can state the entry method; see emergency contact card and medical summary.
• Balance risk: a parent with dementia who wanders may need extra security, but must never be locked in; see below.

Never lock someone in

It may be tempting to lock a person with dementia inside to stop them wandering. This is dangerous and, in many circumstances, unethical or unlawful. In a fire, gas leak or medical emergency, a locked-in person cannot escape and rescuers cannot reach them. It also causes fear and distress.

Safer approaches:

• door chimes or sensors that alert a carer; see door sensor guide;
• camouflaging doors with a curtain or mural;
• placing locks or latches in a way that slows a confused exit, but allows a responsible adult to open them quickly, and never when the person is alone;
• supervision and a calm daily routine;
• ID and a GPS device; see wandering and dementia safety.

Discuss any extra locks with the doctor and the family, and follow fire safety advice; see smoke and gas safety for older adults.

Digital and smart locks

Digital locks open with a code, card, fingerprint or phone, and remove the need for keys, which suits many older people and lets families grant access to carers. Cautions: a flat battery or power cut can lock people out, so choose a lock with a low-battery warning and a mechanical key backup; choose a non-obvious code and change it when staff change; a person with memory problems may forget a code; protect any app with a strong password; make sure the door always opens from inside without a code; buy from a reputable maker and have a locksmith fit it, after checking society rules; see spotting fake or poor quality care products.

Visitors: safe habits at the door

Most doorstep fraud depends on getting through the door; see preventing doorstep scams and phone fraud. Check before opening using the peephole or intercom, use the chain, ask for identification and verify it by phoning the organisation on an independently found number or through building security, and never let in anyone you did not invite. It is fine to say "Please come back when my son is here". Never hand over money, jewellery, bank cards or OTPs, tell building security which visitors to expect, and if in doubt, do not open; call a neighbour, security or 112.

Windows, balconies and other entries

Windows and grilles should open from inside in an emergency, with keys accessible. Balcony doors should be secure but easy to open from inside; see garden, balcony and terrace safety. Back and ground-floor doors often get less attention, so check them, and use a guard on the letterbox so door handles or keys cannot be reached.

Fire and falls at the door

In a fire the person must be able to leave quickly, so keep the route clear and doors easy to open from inside; see smoke and gas safety for older adults. Many falls happen when rushing to answer the bell, so keep a chair near the door, use an intercom, and encourage an unhurried "I'm coming"; see panic pendant buying guide and what to do after a fall.

When to ask a professional

Ask a locksmith or security adviser to inspect doors and recommend locks that are secure but openable in an emergency. Ask the society management about rules and security staff. An occupational therapist can advise on locks and aids for people with weak hands. A doctor can advise when a person's memory or safety awareness is a concern. A police station can advise on local security. For information on services for senior citizens, call Elderline 14567. In an emergency, call 112.
