But electromechanical locks have a ton of attack surfaces. |

In my opinion there are not any dual entry type locks on the market that are reliable. Half the time that light had battery connection issues and wouldn't work. |

I have a Pretty close relationship with several people there, and everything being instituted is because they want the customer's to be happy. This whole thing is going to make me a ton of money in a few years.

But electromechanical locks have a ton of attack surfaces. I do think they did away with the light because it would always flicker and the connection tabs for it were a problem. I personally experienced it a few times. I think it actually used its own 1032 battery also. There are not any spike points for that lock in the keypad or the keypad connector. They are all on the board, and the board is located in the upper corner of the lock. Basically you have to drill the hard plate to get to the board, and if you are doing that you are better off drilling and exploiting the mechanical vulnerabilities of that lock instead of the electronic ones. My Buddy Lance wrote this 455 page book on spiking electronic locks. I looked over the xtreme pretty thoroughly in it. Ironically its on the front cover I am looking forward to taking his class in October on spiking locks. He walked me through one on a high security safe last week. We opened it through the cable hole in the safe.https://www.lockmasters.com/electronic-safe-lock-enspyklopedia |

That book looks VERY promising. I eagerly await the bootleg on the torrent sites. Didn't lockmasters get bought out recently? They used to be the tier two for all the .gov types to go Learn Stuff. Meanwhile, I've been waiting patiently for one of the SAVTA dropouts on youtube to start buying all the wish/temu diamond bits (or whatever the actual term was) and tell me how they stack up to the more expensive ones. I am no longer actively interested in this stuff, but it's fun to check in occasionally... |

The thing was rock solid, and in all their infinite wisdom lagard discontinued it. I think 3035 is just the keypad part number, I would need to know what lock body it is paired with. The X10 is flashy, and there's a big price tag that comes with that. Its not worth the money in my opinion. |
