Arched Door Closer?

I’m looking to buy an arched door closer. What specs are needed so I purchase the right one?

What's the shape of the arch? Normal door closer installations require the door closer arm to clear the top of the door during opening. If the door arch is almost flat, then a standard door closer can be mounted on a slight angle. Any door closer that has spring power strong enough for the weight of your door can be used.

If the arch is similar to the one pictured in our Special Purpose Door Closers article, then a special bracket must be used along with a parallel arm system for the door closer. For this installation, the closer must be mounted on the side of the door opposite of where the hinges are mounted. Parts for this installation are special order from a builders hardware or locksmith dealer and aren’t something that can be ordered "off the shelf" on the internet.

Blank Transponder Key?

I bought a "blank transponder key” from a local locksmith. I tried to program it, but it didn't work. Is there a way I can find out that I was sold just a regular key (no chip) without cutting it open?

-  Peter Andrach

Nontransponder keys often have a number stamped on the key. If any information is printed on your key, I might be able to determine whether it's a transponder key. If no information is stamped on the key, a special tool is available that professional locksmiths use to check for the existence of a transponder without damage. There's no nondestructive way to determine visually whether a transponder is present.

Even though you might have had a correct transponder key, if programming wasn’t done correctly, your transponder might be ruined and can’t be reused. The best idea is to find a professional locksmith who can furnish the key, do the programming and stand behind the work.
