  • Lock Terminology, the “Standard Lock”

    Effective communication is difficult, and it becomes even more difficult when we must describe something we don’t understand. People often call me asking about how much this or that service will cost and I respond asking details about what products I will be interacting with. A good example is whether somebody wants me to unlock…

  • Install August Electronic Lock on Multipoint Trim

    For years I have told people that electronic locks are not really made for multipoint lock door preps. Only recently have the manufacturers started offering extremely expensive replacements for their multipoint locks that work with keypads and they are thousands of dollars. There are other silly setups like a Burg Wachter euro cylinder that used…

  • Changing the Master Key Without Changing Tenant or User Keys

    God forbid the dark day comes when your building’s master key is compromised. Perhaps it was forgotten in a lock, carelessly left on a desk, or was in a stolen purse. However it was lost, somebody has it and they may mean to use it to commit some crime. Hopefully only petty theft, but possibly…

  • Lock battery fail – you ought to use AA batteries

    Saw this one today, customer bought a house and wanted me to rekey all of their locks, was wondering why the electronic lock didn’t work. I have never seen this in my life. You pulled AA batteries out of it, why would you put noticeably smaller batteries in it? AA and AAA alkaline batteries do…

  • Repairing a Door Frame, Emergency

    Got called out to fix a kicked-in door downtown. It was a wild night with Pres. Biden visiting town, an escaped zebra running around in the mountains and the base level anarchy that occurs in downtown Seattle on any given day. It was no surprise that a Belltown apartment building’s door got kicked in. The…

  • Armor Concepts’ Door Armor: A Review

    I don’t want to sound like a shill but let’s get this out of the way first: I think the “Jamb Protector” these folks make is probably the best security improvement most people can make if they already have a decent deadbolt and they install it properly. I have been installing these for years, before…

  • Landlord Tenant Laws and Do Not Duplicate Keys

    Update: as expected I confirmed that this is hogwash, landlords are not required to use a restricted keyway for rentals. There is nothing in the Washington State RCW’s that mention this requirement. Here is The Residential Landlord Tenant Act. Today somebody called me asking about restricted keyways for his rental unit. I warned him that…

  • Where to get antique-y woodscrews

    You’re here because you have a pretty nice old antique lock, but successive visits by helpful tradesmen or well-meaning husbands clearing a docket of tasks as beer thirty approaches have filled the holes on your lock’s trim with a motley selection of steel screws, lag bolts, nails, etc. These look like so many small and…

  • The blessing of IC cores

    Sometimes I get called out to rekey a commercial building (less frequently it’s a restaurant, apartment building or house) that has special locks using SFIC cores. They look like little figure eight lock cylinders and sometimes they say BEST, Arrow, or Falcon on them just above where you stick your key. The customer usually looks…

  • How safe are safes?

    It isn’t often that news about safes and safe locks hits the mainstream. Recently it came out that Liberty Safe had provided a factory code to the FBI to open up a gun safe owned by one of the accused in the January 6th imbroglio.; not with a court order but with a search warrant.…
