Merrimack is laid out around business parks and the Everett Turnpike exits rather than a dense downtown, so the doors we are asked about tend to be a glass front on an office unit, a personnel door beside a loading bay, and a staff entrance nobody can see from the road. Each of those needs a different answer, and a single quote that treats them the same is a quote worth questioning.

Mr G Lock and Keys installs and repairs access control across Merrimack, NH for office units, warehouses, clinics, shops and homes. We work on systems we fitted and systems we inherited, and we start at the door rather than at the catalogue.

Merrimack doors and what they ask for

A personnel door next to a loading bay leads a hard life: it takes weather, it gets held open with a pallet, and the closer usually gives up before anything electronic does. For those we favour a robust strike, a heavy-duty closer and a reader mounted out of the traffic line, with a door position switch so you know when the door has been left standing open.

Office fronts are the opposite problem. They need to be unlocked during business hours and secure the moment the last person leaves, which is a scheduling job more than a hardware one. Get the schedule right and nobody has to remember to lock up.

• Readers and keypads on office unit entrances and staff doors
• Warehouse personnel doors with heavy-duty strikes and closers
• Door position switches so a propped door is visible
• Smart locks and keypads for houses and rental properties
• Scheduled unlock and lock for trading hours
• Repairs, battery backup and user-list rebuilds on existing systems

The Merrimack repair calls

Propped doors cause most of the trouble here. A door held open all afternoon in July is a door that has been out of the closer for hours, and by the autumn the alignment has moved enough that the strike misses. A door position switch and a short alarm delay fixes the habit faster than a memo does.

After that it is power. Units on long runs from the electrical panel end up with undersized supplies, and a marginal supply shows up as a reader that works in the morning and stutters by late afternoon. Measuring at the door rather than at the panel usually ends that mystery in one visit.

Signs a Merrimack building has outgrown its keys

• The loading bay door is propped whenever a delivery is due
• Staff share one code and nobody remembers when it changed
• Your unit was re-let and the previous tenant kept credentials
• Readers behave differently at the end of the day than at the start
• You cannot see whether the back door was left open overnight
• Contractors need access on set days and you are meeting them to let them in
