What Electronic Door Lock Would You Buy?
zentigger asks: "I work for an ISP that supports internet in several dozen remote areas. Our POPs are typically fairly small shed-like structures, with a couple racks of equipment. For the most part, we can manage this stuff in-band, but frequently we need to have a local agent physically access the equipment for some minor maintenance work or adjustments. As time goes on, the shuffle of keys is becoming farcical and expensive. What we need is an electronic lock of some sort that can be reprogrammed remotely (preferably from a remote console via serial or directly via ethernet) that will stand up to extreme weather. Google certainly turns up lots of glossy brochures — although I don't see how they can -all- be 'The heaviest duty lock you can buy!' Does anyone have good experiences with any particular products or perhaps other means of dealing with the key shuffle?"
Sargent & Greenleaf are *THE* stanrdard when it comes to electronic locks. See here.
A while back I did some consulting for a somewhat remote municipality, who was in your exact same situation. They had small "equipment sheds" located throughout the region, and were having problems maintaining physical access. Their solution was to invest in a bunch of programmable electronic combination locks that they could reprogram as people were fired and/or promoted and not have to go through the whole rekeying process. This created an entirely new problem: People forgetting access codes that changed every several months. These workers worked around the problem the only way they could: Prying open the doors with tools, breaking the doors and sometimes the locks in the process. This forward-thinking municipality ended up footing the bill for the lock retrofit, a bunch of broken doors, and ultimately a return to standard keyed locks. FYI, YMMV...
I have a complete electronic defense system for my home and I am currently upgrading the AI. It was slow going at first, the AI kept requesting to be given a name. Eventually i gave in and called it Skynet and things have been going quite well, although the Asimo I hooked up to it does like to chase me round the house a lot trying to taser me. I am going to ask one of my mates at the NSA if one of their global domination scenarios can connect and defeat it as a final acceptance test. Should be cool.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
Most companies I see use HID or S&G for card access. I personally would recommend HID (one of their newer card reader lines that use two-way authentication).
For mechanical lock backup, go with Medeco, Mul-T-Lock, or Abloy. All of which are immune to bumping, are restricted in key duplication, but keys are still decently available when you need copies made at a locksmith with your card.
Lastly, if you want a solution that is a hybrid, requiring only cylinders changed rather than lock hardware, you might consider the Mul-T-Lock CLIQ series. The CLIQ keys are mechanical and electronic, and the reader is in the cylinder, so no wiring of doors is needed. To remove a key from the authorized list, you just code the programmer key to remove it, then walk around and stick the key in the appropriate doors.
I used to use a system much like you describe. I used to work at a major international airport, which secured some private areas from the public with a cipher lock. It had rocker buttons, five of them, at the bottom of a metal "butter tub". You could stick your hand in there and look inside and see the labels on the buttons, but once you'd seen it once, you didn't need to look again. The rocker buttons were centered and if you press one way it might be a '1' and the other way was a '6', I think.
A more interesting system was on the front door to my office - a 9-digit keypad where the numbers were lit up in a dot-matrix format. You could only read the numbers standing in front of it, and they would change each time you walked up to it. It was very cool, but they stopped using it in favor of ethernet-programmable fingerprint readers.
There are a lot of options. The tougher part is weatherproofing any of these solutions. The more fancy electronics you have, the more important keeping water out becomes. Good luck!
Just my $0.55 (US inflation, 1774-2008, for $0.02)
With high-security systems, the blanks are under patent. Only locksmiths who service those locks have access to them. With most systems, you end up with regional distributors, and if you walk in asking to get a copy made, they'll recognize it as one of theirs and confiscate it- and inform the true owner of what happened. I've actually seen that happen- it's pretty unfortunate for the guy working for a major bank to lose his job over that sort of thing. They can then mike the key and determine whose it is; if it is stamped with a serial number, it's even easier.
All bets are off if a machinist is available to duplicate it. This is made very difficult with sidebar locks such as ASSA, or with odd keys such as Abloy. A machinist would also have to duplicate the wards and angle cuts if duplicating Medeco keys.
So while the possibility is there, I have yet to hear of it happening.
Look at what universities use. They have thousands of users that need access to various areas, but only to very specific areas around campus. This includes students as well as staff.
They need to control who has access, as well as when access has been gained. Most employers now use some kind of ID system, the 'access keys' could be included in the ID. It could be as simple as RFID to magnetic stripes. You could also combine these with keycodes chosen by the individual users. With this dual level of authentication, the keycodes would not need to be updated regularly because of the dual authentication.
You could use one of your onsite servers to control access and log access. These servers could be updated in real time. The only worry would be that the server could not be updated quickly enough after an employee was fired. This is where HR comes in, if you have your system immediately revoke ID's upon employee termination, terminated employees would not be able to gain access. On the off chance that the servers could not be updated due to communication problems, the server that controls access logs would show that the terminated employee gained access to a facility after their rights had been revoked. Combine this with video surveillance you will have both digital and pictorial proof of the illegal access. In a worst case scenario, one of you security officers would need to physically show up to the site to allow access to someone that has the right to access the facility, but the inability to do so.
