Why turnover is the best time to improve security

Between tenants you have a rare window. Doors are accessible, schedules are flexible, and no one else is relying on the locks each night. Any adjustments you make now will protect the property, simplify access for the next renter, and reduce after hours calls later. This guide covers mechanical security, code and key practices, basic lighting, documentation, and clear handoffs that keep everyone aligned.

Quick start: a 12 point turnover checklist

1. Rekey or replace every keyed cylinder on exterior doors and any keyed windows or outbuildings.
2. Test deadbolt throw and adjust strikes so the bolt seats fully without lifting or slamming the door.
3. Upgrade strike plates with longer screws into framing and add hinge side screws for stability.
4. Inspect door viewers and latch guards then install or replace as needed for visibility and pry resistance.
5. Reset all keypad codes and remove old users on smart locks. Replace batteries with fresh, high quality cells.
6. Secure sliders and windows with secondary bars, track pins, or upgraded sash locks where appropriate.
7. Evaluate lighting at entries and parking. Install bright, shielded, motion activated fixtures if areas feel dim.
8. Label keys discreetly and build a simple key chart. Never include an address or unit number on a tag.
9. Check garage and storage hasps, padlocks, and remotes. Reset remotes and code pads.
10. Document with photos of door edges, hardware, and window latches for your records and later comparison.
11. Review alarm or camera settings where present. Remove old users and confirm privacy boundaries.
12. Prepare a welcome sheet that explains lock operation, keypad etiquette, and how to request help.

Rekey vs replacement: choosing the right path

Rekeying changes which key operates a lock while keeping the existing hardware. It is the fastest way to reset access after move out and is often the best value when hardware is in good condition. Replacement makes sense when a lock is dated, mismatched, or worn. Consider a mix. For example, replace a tired front door deadbolt for visual impact and strength, then rekey the side and back doors to the new pattern so the tenant receives one convenient key.

• Good candidates to rekey: modern deadbolts in decent shape, matching brand cylinders, interior garage door locks.
• Good candidates to replace: wobbly knobs, flaking finishes, sticky latches, bargain locks that do not match others.
• High security option: restricted keyways improve key control since duplicates require authorization.

Deadbolts, strikes, and hinges: the feel of quality

A strong door should close gently and lock with a confident turn. That feel comes from alignment and anchoring. Replace flimsy strikes with reinforced versions and use longer screws into the stud. On the hinge side, swap one short screw per hinge for a longer screw that reaches framing. These small upgrades distribute force and keep doors square through seasonal changes. Finish by confirming weatherstripping does not fight the latch. If the door requires a lift to lock, adjust before move in.

Keypads and smart locks: convenience with good hygiene

Keypads are excellent for turnovers. Codes can be changed in minutes, and you can set a short term code for vendors while the unit is empty. Follow simple hygiene rules:

• Reset to factory where appropriate, then add the new tenant as the primary user.
• Use unique temporary codes for cleaners and trades, then remove them when work is done.
• Enable auto lock timers suited to the door location so accidental unlocks relock themselves.
• Install fresh batteries and note the date inside the cover. Provide a spare set in the welcome kit.
• If you prefer no apps, choose models that store codes locally. If remote control helps, add a bridge after confirming Wi Fi strength.

Key control: simple systems that scale

Keep your key chart short and clear. Issue only the keys a tenant needs. When you rekey, record the new key code, how many copies exist, and who holds them. Stamp keys with an internal identifier rather than an address. If you manage several doors across multiple buildings, consider a basic master key plan that allows maintenance access while tenants keep individual keys. If duplication control matters, use restricted keyways and track authorization cards in a secure file.

Windows and sliders: the overlooked entry points

Windows are often the weakest link. Confirm every latch pulls sashes tight. Add secondary locks or track pins to sliders and basement windows. For ground floor sliders, a steel bar or pin prevents lift out. Check that screens fit well so tenants are less tempted to prop windows with risky objects. A few careful minutes now prevents nuisance calls and reduces the chance of a window left ajar at move in.

Garages, sheds, and utility areas

Do not forget spaces outside the main unit. Garages may have keypad openers and side doors with simple latches that deserve an upgrade. Sheds need sturdy hasps and weather resistant padlocks keyed into your system when possible. Utility closets and meter rooms should be clean, labeled, and on a separate key or code that you control. When a tenant moves out, reset remotes and any standalone code pads to prevent accidental carryover access.

Lighting and visibility

Good lighting improves safety and comfort. Add bright, shielded fixtures near the primary entry, parking, and mailbox areas. Motion activation works well around driveways. Choose warm color temperatures for residential entries to reduce glare at night. Replace dim or flickering bulbs and clean lenses during turnover so photos and showings look better and tenants feel welcome on day one.

Cameras and alarms: privacy first and clear rules

If exterior cameras or an alarm system are part of the property, reset accounts, update contacts, and remove old users. Share a simple guide that explains what is monitored and what is a tenant choice to enable. Avoid cameras inside the living space. Keep privacy boundaries clear and confirm that any recording devices are disclosed and placed only in appropriate areas such as exterior entries or common spaces.

Documentation that saves time later

Photos and short notes reduce confusion. Capture images of each door from inside and outside, a close up of the latch and strike, and the closed position that shows alignment. Note any special parts or finishes. Keep a simple log listing lock brand, key code, battery install date for keypads, and any reinforcement used. When issues arise months later, these details speed decisions and reduce repeat visits.

Working with vendors during vacancy

While the unit is empty, trades often need access. Use a vendor code on the keypad or a lockbox in a discreet location. Share clear hours and remove the code when work is done. If you prefer keys, issue a time bound key and log it. Vendors appreciate predictable access and you keep a record that supports clean, accountable turnover.

Tenant onboarding: teach the small habits

A one page welcome sheet goes a long way. Include where to find spare batteries for keypads, how to use the mechanical override key, and who to contact for after hours help. Suggest simple habits like closing the door fully before turning the deadbolt, using light pressure on keys, and reporting rubbing or sticking early. These pointers prevent premature wear and remove friction from daily life.

Baseline, better, best: three upgrade bundles

Common mistakes to avoid

• Skipping rekey because the tenant returned keys. Copies may exist that you do not know about.
• Leaving mixed brands and keyways across doors. Tenants end up with a pocket full of keys and more confusion.
• Mounting hardware without reinforcement. Screws into thin jamb material loosen under daily use.
• Forgetting sliders and basement windows. These are frequent trouble spots.
• Using one universal vendor code season after season. Rotate codes and remove them at job completion.

A simple turnover timeline you can reuse

1. Day 1 Inspect all entries, windows, garage, and storage. Photograph and list parts needed.
2. Day 2 Rekey or replace cylinders. Reinforce strikes and hinges. Adjust latching and weatherstripping.
3. Day 3 Install or reset keypads. Program admin and guest codes. Replace batteries and label inside the cover.
4. Day 4 Add lighting and viewer upgrades. Check sliders, track pins, and window locks.
5. Day 5 Final test with the key set and codes the tenant will use. Prepare welcome sheet and key chart.

Legal and policy notes in plain language

Security choices should respect local rules and lease terms. Keep egress simple from the inside. Share how to reach you for urgent issues and how lockouts are handled. If you plan to use exterior cameras, disclose their location and purpose. If you manage multi unit buildings, align upgrades with building management and ensure consistent standards across units. For specialty hardware such as double cylinder deadbolts, confirm what is permitted before installation and consider alternatives when glass is near the thumb turn.

Handing off to your next tenant

On move in day, walk the tenant through the main entry. Demonstrate a full deadbolt throw and how to close the door without force. Review keypad entry and battery replacement. Provide the key set and list how many copies exist. Show where to store the spare and how to reach you for help. This five minute tour solves small issues before they start and reinforces that security is a shared practice.

Securing a rental between tenants is less about expensive gadgets and more about consistent habits. Rekey or replace, reinforce and align, reset codes, document, and teach the basics. Follow this routine and your next turnover will be calmer and your tenants will feel right at home from the first night.
