Locksmithing/Ideal Security Double Sided deadbolt


I have a very old double sided deadbolt (Ideal Security brand) on my door. We broke the key off in it & need to remove it. It has no visible screws, but there is a notch next to the piece the key goes into on the inside face of the door. Can you tell me how to remove the deadbolt to get the broken part of the key that's in there without damaging it so we can still use it? As well, would we need to align it when putting it back on &, if so, how do we do that?


If the key broke off on the inside and you can still operate the lock from the inside you're in luck.

First option: use a small drill bit - 1/16" or so - and manually thread it into the ley hole next to the broken key then pull straight out.  Do NOT use a drill.

Option 2: Turn the key cylinder (the part the key goes into) until it stops then insert a strong piece of metal into the slot that is open (one should open when you turn the cylinder).  Push hard until it releases the retainer pin then pull the assembly off - you may or may not feel the retainer release.  If that doesn't work, turn the key the other direction and try the other hole.

Option 3: call a locksmith and have them remove it then remove the broken key and reinstall it.

Before you try option 2 I'd advise purchasing a new deadbolt in case you can't get the old one back on.

You might want to replace the lock regardless of the outcome:
1: double cylinder deadbolts are a life / safety hazard because you can't exit if it's locked without a key; and
2: your lock is no longer made, parts are not available and your broken key might be a sign of wear in the lock which could cause future issues and further life / safety concerns.

I do not answer Safe or automotive questions. Period. I am knowledgeable in almost every area of Locksmithing. This includes locks, keys, lost keys, residential and commercial lockouts, rekeying, masterkeying, high security locks, access control, electric locks, security cameras and home safety. I have been running an online business since 2004 where I sell all types of lock and security hardware to everyone from apartment renters to business owners to the US government. Before that I started a locksmith service in 1999. I deal with many types of security equipment including high security safe locks, heavy duty padlocks, exit devices, biometric readers, electric strikes, magnetic locks, full surface hinges and I only sell what I personally stand behind 100%. The online business has given me a more in-depth look at the locksmithing industry, helping me to learn more about each and every product that I offer, as well as products I don't have but end up finding for customers to solve any issues they have with security or door hardware.

Please don't submit any automotive or safe questions as these aren't areas that I can help in.
