Its really simple if you are using most any brand of Electronic Mag-locks. Go down to your local hardware store and pick up a pair of Vice-Grips. You can 'pinch' the Sex bolt holding the armature in place and unscrew it.
If you use the 'weld' Loctite you will have issues. We use the next one down that holds well but will let you remove with tools. There will be naysayers of course, but I have actually done this.
WA - La door opens.
I have to say if I read this correctly, this is wrong on several levels. I don't know where you are, but you should never install or tolerate the installation of EM locks in a manner that users have to break the glass to get out. This violates the Life Safety Code 101 in its entirety not to mention common sense. You should install a mechanical means of egress (usually a big green button) adjacent to the door that is tied directly to lock power. Pushing the button interrupts the power if the controller fails. You absolutely must provide a means for escape.
With the other poster, if you have an EM lock that can be removed that easily from the outside, that is another total failure on someone's part.
Second, you should seriously consider replacing or repairing that controller. It is either bad or is a POS.
Lastly, we use a WEB Relay tied to lock power as a backup. Never had to use it, but we test it annually and it works like a snap. We can open the door with any mobile device that has the app or a desktop, from hundreds of mile away. Only two people have access to it. As long as you have internet access at the facility, it works.
Like I said "Most do not like to admit this but it is what it is"
Judging by the sound of and the manner of this install my guess is you don't have a backup battery for the Maglock. the easiest and least destructive solution is to turn off the power source to the lock.
Second easiest is to drill the sex-bolt or better off if you have a grinder just cut off the head of it. if you do it carefully enough you will not damage anything other than the bolt itself.
Sounds like a "low bidder installation"
Proper installation of the correct equipment would correct the problem.
1. Install a Rex sensor with two relays. One to send a signal to the panel Rex input, and one to break the power to the mag lock in case of panel failure.
2. For redundancy, Install a pneumatic push button to break power to the mag lock.

1. EM/Maglocks should not be used in any application where breaking glass or the door is requisite of egress. In blunt terms; this is not secure, it is a deathtrap.
Use Request to Exit devices on the inside/secured side.
2. OKC - or 'Outside Key Control' switches are often used to interrupt power to the maglocks from the outside. It essentially is a power switch that is keyed with a typical mechanical key that can be turned to manually cut power if the inside controller is unresponsive:
Actually all you have to do is determine if the egress is motion based (glass door helps to see this) and stick something between the doors and wave it back and forth. I have done this with a large desk calendar. FYI I did NOT install this door and would have created a more secure situation. I have had better, but not perfect, success with floor mats. This isn't the emergency procedure intended but I thought I'd throw it out there anyway.
An audible "scream cover" over a button is typical for releasing a maglock in an emergency. It's loud enough to be intimidating to people who forgot their ID and works to alert others its being used.
