Rental properties face unique security challenges in Colorado. Between tenant turnover, lost keys, unauthorized copies, and outdated hardware, many landlords are unknowingly exposing themselves to liability — and tenants often don’t know what their rights or options are.

As locksmiths serving Aurora, Parker, Centennial, Castle Rock, Englewood, and surrounding areas, here’s what we recommend for both landlords and tenants.

For Landlords

1. Rekey After Every Tenant — Non-Negotiable

Colorado does not explicitly force landlords to rekey between tenants — but you should always do it.

Why rekey?

• Former tenants may still have copies
• Relatives, babysitters, ex-partners, or contractors may have keys
• Keys are inexpensive compared to liability
• Rekeying ensures YOU control access 100%

This is the #1 way to prevent break-ins, “mystery entries,” and legal claims.

2. Avoid Standard Keys — Use Restricted Keyways

Restricted key systems prevent unauthorized duplication at hardware stores.

Benefits:
✔ Tenants cannot copy keys without your permission
✔ Eliminates hidden duplicates
✔ Increases accountability
✔ Reduces rekey frequency

Great brands include Medeco, Mul-T-Lock, ASSA Abloy, and high-security Schlage systems.

If you own multi-unit buildings, restricted keyways are essential.

3. Smart Locks for Multi-Tenant Properties (Used Properly)

Smart locks can be great for rentals, but only when installed correctly.

For landlords:

• Avoid WiFi-dependent models
• Choose heavy-duty commercial smart deadbolts
• Give every tenant a unique PIN
• Delete codes immediately when tenants move out

For duplexes, townhomes, and small apartment buildings, smart locks reduce your maintenance load and improve access control.

4. Door & Strike Plate Reinforcement

Most rental break-ins in Colorado happen through kicked-in door frames — not lock picking.

We recommend:

• 3″ screws into strikes and hinges
• Heavy-duty deadbolts
• Reinforced metal wrap plates
• Door jamb armor for older buildings

These upgrades are inexpensive but drastically improve security.

---

5. Exterior Camera Coverage (Common Areas Only)

Colorado law protects tenant privacy.
Landlords may install cameras ONLY in:

• Parking lots
• Shared hallways
• Entrances
• Storage/common areas

Cameras cannot be placed inside the rental unit or aimed in a way that violates reasonable privacy.

If you want commercial-grade cameras (e.g., Milesight, Uniview, Hanwha), we can help choose the right models.

For Tenants

1. Ask for a Rekey When You Move In

Many tenants don’t realize they can simply request it — and landlords who care about security rarely refuse.

---

2. Add Portable Security Devices (Allowed in Colorado)

You can use:

• Portable door jammers
• Pin locks on sliding doors
• Window security bars (non-drilling)
• Smart cameras inside your unit only

These improve security without altering the property.

---

3. Keep Track of Your Keys

Lost keys are a major reason for disputes and fees. Treat the keys like valuables — because if they fall into the wrong hands, they can compromise your home.

---

4. Report Door or Lock Issues Immediately

If the door is sagging, the lock sticks, or the deadbolt doesn’t fully extend, request maintenance fast. A failing lock is both a security and safety risk.
