Why Glendale Property Managers Are Switching to Master Key Systems
We got a call last month from a property manager on East Colorado Street who was carrying 37 keys on a single ring. Thirty-seven. One for every unit in her building, plus the laundry room, storage cages, and the rooftop access door. Her cleaning crew had an identical set. That’s 74 keys floating around Glendale for a single mid-size apartment complex.
She asked us about a master key system in Glendale — the same setup hotels use so housekeeping can access guest rooms with one key while each guest still has a unique key that only opens their own door. We installed one for her building in a single afternoon. Now she carries two keys: a grand master and her own office key.
If you manage rental units, an Airbnb, or a commercial building anywhere in Glendale, here are seven things we think you should know before setting up your own system.
7 Tips for Getting Your Master Key System Right
1. Map Out Every Door Before You Call Anyone
This sounds basic, but almost nobody does it. Walk through your entire property — every unit door, every common area, every utility closet — and write down what exists. We’ve worked on buildings near the Americana at Brand where the owner forgot about a basement storage room that hadn’t been opened in three years. If it’s not in the plan, it’s not in the system, and you’ll be paying for a retrofit later.
2. Decide Who Gets What Level of Access
A hotel-style master key system works on a hierarchy. Think about it like this:
- Grand Master Key — opens every lock in the building. This is yours, the owner’s, or the building manager’s key.
- Master Key — opens a group of locks. Your cleaning staff gets this. They can access all residential units but not your office or the electrical room.
- Individual Key — opens one lock only. Each tenant gets this for their own unit.
For a property on North Central Avenue or a multi-unit building in Adams Hill, you might want your maintenance person on a different master than your cleaning crew. That way your cleaners can get into apartments but not the mechanical room on the roof.
3. Use Restricted Keyways — Seriously
A restricted keyway means the key blanks aren’t available at your local hardware store. Nobody can walk into the Home Depot on San Fernando Road and duplicate your master key. This is the single biggest security upgrade in the whole system. We use Mul-T-Lock and Medeco restricted blanks for most of our Glendale master key system installs. Copies can only be made through us, with your written authorization.
4. Keep a Key Log Like Your Business Depends on It
Because it does. Every key issued to cleaning staff, maintenance workers, or tenants should be tracked with a name, date, and key number. When someone on your cleaning crew leaves, you’ll know exactly which key to collect. We provide a simple tracking sheet with every installation — nothing fancy, just a spreadsheet that works.
5. Plan for Tenant Turnover
Glendale’s rental market moves fast, especially around the Galleria and along Glenoaks Boulevard. Tenants move in and out. With a well-designed master key system, you can rekey a single unit without touching the rest of the building. The master key still works, every other tenant’s key still works, and the new tenant gets a fresh key that the old tenant’s key can’t open. We handle these rekeys regularly for property managers across Glendale — takes about 15 minutes per door.
6. Don’t Forget the Support Spaces
Package rooms, offices, pool gates, parking garage pedestrian doors — all of these can be folded into your master key hierarchy. A building we service near Verdugo Park has the pool gate on the master so cleaning staff can access the pool area for maintenance, but individual tenant keys don’t open it. Tenants get a separate pool fob. It’s a small detail, but it gives you real control over who goes where.
7. Get It Done by a Local Locksmith Who Knows Glendale Buildings
Master key systems require precise pinning and careful planning. One wrong pin stack and your tenant’s key opens their neighbor’s door. We’ve been called in to fix botched master key jobs from out-of-area companies who didn’t bother to verify the system after installation. Our team works across Glendale daily — from office buildings on Brand Boulevard to apartment complexes in Rossmoyne and Crescenta Highlands — and we test every single lock before we leave.
What a Typical Installation Looks Like
For a 20-unit apartment building, the whole process usually takes one day. We show up, assess the existing hardware, pin the cylinders to your approved key hierarchy, cut all the keys, test every door, and hand you the key log. Most of our Glendale locksmith services clients are surprised at how straightforward it is.
The cost depends on how many doors and how many access levels you need, but for most Glendale properties we work on, it’s significantly cheaper than installing an electronic access system — and there are no batteries to replace or software to update.
