What is lost key coverage?

Lost key coverage is an endorsement to general liability insurance that could help pay for the cost to re-key locks or replace hardware if client keys left in your care are lost or damaged. It can help when a simple mistake puts a client’s building security at risk.

Without lost key insurance, you may have to pay out of pocket to secure a customer’s property. If you opt to add lost key coverage to your existing general liability coverage, this endorsement could help with expenses around:

• Re-keying existing locks: Adjusting internal tumblers so the lost keys no longer work.
• Installing new lock cylinders: Replacing the core components of the locking mechanism.
• Providing new master keys: Issuing high-security replacements for building managers.
• Full lock replacement: Swapping out hardware with new locks similar to the existing lock.

While “lost keys” might sound universal, this insurance is specifically designed for buildings and real estate security rather than personal or commercial vehicles. If you lose the keys to a business van or a client’s car, that’s usually handled under a commercial auto policy or garagekeepers liability.

Who needs lost key insurance?

Any professional who works with secure client property could benefit from this additional coverage. If your work involves temporary possession of a customer’s building access, you are likely a prime candidate for this protection.

• Cleaning and janitorial services: These pros often manage master keys or fobs for entire apartment complexes or office parks, where a single key replacement compromises the security of every tenant.
• Construction contractors: Managing lockbox access or site keys for new builds means a lost key could force a developer to replace all exterior hardware to maintain safety.
• Property managers: Ensuring that your hired subcontractors carry this coverage protects your building’s overhead from unexpected locksmith invoices.
• Real estate agents: Misplacing a key during a busy day of showings, on top of handling keys for multiple listings carries a high frequency of risk.
• Pet sitters and dog walkers: Entering private homes daily while owners are away.
• HVAC and plumbing technicians: These contractors are often granted unsupervised access to homes or mechanical rooms — and are responsible for securing the area when they leave.

Why you might want to add lost key coverage to your General Liability insurance

Many business owners assume a standard general liability policy has them covered if a client’s keys go missing — after all, this policy can help with customer property. However, there’s often a care, custody or control (CCC) gap in standard liability coverage. 

Standard policies typically exclude coverage for property that is in your temporary possession or under your direct management. Because you’re the one holding the keys to the building, the insurance company could view someone else’s property as being under your responsibility — meaning your client’s claim for re-keying could be denied.

That’s why key replacement coverage could help with the costs associated with a security breach, such as:

• Locksmith labor: Professional fees for emergency re-keying services can cost hundreds of dollars per hour.
• Hardware costs: High-quality lock cylinders and master key systems can be expensive to source and install.
• Total building security: In large complexes, losing one master key can trigger a requirement to re-key dozens of individual units to ensure tenant safety.

Lost key coverage claim example: The 20-door headache

Here’s a common situation for cleaning and construction professionals:**

Imagine you are a janitor responsible for a 20-unit apartment building. The landlord gives you a master key to access common areas, but at the end of your shift, you realize it’s missing.That key could be anywhere, and now every tenant’s safety is at risk. The landlord is now forced to immediately re-key the entire complex to secure the building.

The resulting bill could get expensive quickly. At quick estimate, that could reach as much as $5,000 once you factor in emergency locksmith labor, new cylinders and replacement master keys. And if the keys were in your control or in control of your employees, the landlord expects your business to foot the bill.

Here’s how those numbers look when you compare an uninsured mistake to a protected business with a covered claim:
