I purchased a Sentry Safe biometric pistol safe several years ago. It's a nightstand pistol safe using key, pin, or biometrics to open. About a year ago, I noticed the lid was only opening 3/4 of the way. It was opening more than enough to grab a pistol out quickly, if necessary. I wasn't really concerned about it then. About two weeks ago, I went to open it to get the daily carry out before work. The hatch barely moved when i slid my fingers over the print reader. I had to use my fingernail to get the safe lid open. "Well that's not gonna work". After a little searching on the interwebz, I found a replacement gas strut. Replacing was very simple and the strut was cheap, 19.99 for a set of two. I'm adding the link to this product. Not sure how many of you have a similar safe, but I figured I'd share if it would help someone to fix the issue I came across.
