What is the best security upgrade for a renter's apartment?

The consensus best practice is to install a renter-friendly, ANSI/BHMA Grade 2 (or higher) smart deadbolt. This provides keyless entry, allows you to control access, and can be easily removed. For comprehensive protection, pair this with a DIY wireless security system that uses adhesive sensors.

How much do apartment security upgrades cost?

Costs vary by type. A simple portable door jammer can be as cheap as $20. A good quality, renter-friendly smart lock typically costs between $150 and $350. A starting kit for a DIY wireless security system usually runs from $200 to $500, with optional professional monitoring services costing an additional $10 to $30 per month.

Can I install a new lock on my apartment door?

You MUST get permission from your landlord or property manager before changing the lock. Most are agreeable if you use a non-damaging smart lock and provide them with an alternative means of access (a physical key override or a dedicated access code) for emergencies, which is often legally required.

How long do the batteries in a smart lock last?

Typically, batteries in a keypad or smart lock last between 6 to 12 months, depending on usage. All major brands provide ample low-battery warnings via the app and on the device itself. Many also include terminals on the exterior to temporarily power the lock with a 9V battery if the internal batteries die completely.

What are the warning signs of a bad security product for renters?

Avoid uncertified, cheap smart locks from unknown brands as they often have weak physical and digital security. Be wary of any security system that requires professional hard-wiring or long-term contracts, as these are not suitable for rental situations. Finally, any lock that requires you to drill new holes in the door or frame is generally a bad idea for a renter.

What the Pros Say

"For renters, the biggest win is a smart lock that uses the existing door prep. No new holes, no problem with the landlord. I recommend models like the Yale Assure or Schlage Encode because they're reliable, easy for a renter to install, and can be swapped back for the original lock in 15 minutes."

Mike Johnson

Certified Locksmith Technician, 15 years

"We see a huge demand from renters who want more control. They don't know who has a copy of their key. A keypad lock solves that instantly. The ability to set and delete codes yourself is the single most important peace-of-mind feature for apartment dwellers."

Sarah Chen

Security Solutions Service Manager

"Look for at least an ANSI/BHMA Grade 2 rating on any smart lock. Grade 1 is commercial-level, but a solid Grade 2 offers excellent residential protection. Also, ensure the app has two-factor authentication to protect against digital intrusion, not just physical."

Carlos Rodriguez

Master Technician & Integrator

"The trend is undeniable: renters are moving beyond simple rekeys. They want integrated solutions. We often recommend a combination: a quality smart lock on the main door and a simple, non-invasive system like SimpliSafe with a few entry sensors. It covers all the bases without violating lease agreements."
