Electronic key card locks

Background- I want to send my kid to a different school next year but the school does not lock their doors. It's an older school with several buildings the kids have to walk to and from. All of the doors are steel except the glass lobby doors. The key card reader locks would make the school much safer.
Anyone here ever work on electronic locks?
The ballpark cost of 18 doors with card readers and one door to "buzz" in visitors?
Can they be retrofitted to a brick building built in the 50's?
TIA

Never installed them but the ones where I work run off my infrastructure. I'm sure you could retrofit the doors. All that's really going on is a card reader reads the card, sends the info back to a central server over cat5 ethernet, the central server logs the requests, and either approves or denies entry. This sends a signal back to the door lock, often an extremely powerful electromagnet, and allows the door to be opened.
All of that could be done fairly easy as it is just cable to be run.
There are other issues involved. Typically there is an internal motion sensor to allow people to exit without swiping. Also safety regulations I'm sure, like in the event of a power outage, they probably have to fail open.

Probably $20k in hardware for the doors and $20k in IT costs. So close to $50k. Probably half that if you go cheap.

Also, if the exterior walls are masonry, face brick or CMU, there isn't really a good way to make them tamper resistant without a lot of demo, shoring, and replacement.

quote:Not quite. There's a panel that goes between the readers and the server. The quality/features of the panel and software is where you'll see the most cost in the system itself. And a panel that can handle 18 or so doors has to be pretty robust. (ETA: Actually, if you're talking about a school with sets of doors in multiple locations, you're looking at multiple panels for each area other wise, you'll be running cables everywhere.) But another poster is right... installing will cost a ton, especially if you're dealing with an old school. Brick, failing infrastructure, etc.

The big issue for a school is who administers the server, panel, readers, software? Because if something doesn't work correctly, do you just prop the doors until you can get contracted IT support out there? Schools typically don't have someone like this on staff.

Cheaper to do Dad Defense....each one of you takes a day off and sits outside of school all day.
I'm no security consultant, but I think the types that have shown to attempt what you want to avoid would be more apt to not try with a live person standing watch.
Not wanting to hijack, but my kids go to a similarly arranged school and interested to hear if I'm nuts- I've considered starting this for a while- I understand there are some schools in CA that already do it.

I'd say about $40-60k, depending on features and options. if you avoid mag locks and use door strikes it will cut costs and be a little more user friendly. The way our setup is configured one controller can control 2 doors so you'd have about 9+ controllers for that setup and a server and the software can be installed on laptops or pcs.
