Changing or updating the cylinder prevents copies of previous keys from continuing to give access to the home or premises. Start with controlling your keys.
After a robbery attempt
We assess damage, cylinder and shield to reinforce the vulnerable points of the door with an appropriate solution.
Theft prevention
We check the cylinder, shield and vulnerable points of the door to reinforce access before an incident.
Safety cylinders
Eight out of ten break-ins occur through the main door, the most vulnerable access point. Reinforce its security with high-security locks and doors to make manipulation and sabotage techniques more difficult.
We work with anti-bumping, anti-pick and anti-drill options, depending on the characteristics of the door and the level of protection sought.
Brands we work with
We also work with leading brands in the sector to guarantee the quality of every solution.

What we check before changing a lock
Not all doors need the same system. We check the type of lock, cylinder measurements, condition of the door, handle compatibility and the existing exterior protection. With this information we propose a replacement that maintains a correct closure and improves security. The proposal starts from your door, not from a standard solution.
Bowlers with property card when the model allows it.
Compatibility with armored, armored and conventional doors.
Installation of protective shields against extraction and drilling.
Attention for homes, premises and communities of owners.
Safety shield and bowler hat: joint protection
The cylinder is a central element of the lock, but the outer shield helps protect it against attack methods such as breaking, extraction or drilling. During the visit we check if the door supports a compatible shield and what level of protection makes sense for your case. Both pieces work best when valued as a set.
Change the cylinder or the complete lock?
If the lock works correctly and the objective is to renew the keys or improve the cylinder, it may be enough to replace the cylinder. When there is wear on the mechanism, damage after an incident or incompatibility with the desired improvement, the complete lock is evaluated. We also check if it is embedded, overlay or multi-point to avoid unnecessary replacement.

The entire experience, from the initial consultation to the final cleanup, was flawless. The team made measuring and ordering quick and easy, guiding me through the design options to provide maximum security without making my house look like a fortress.
Why I was impressed:
Speed: The time between the quote and the installation day was surprisingly fast. The installation itself took much less time than expected.
Professionalism: The installers were punctual, very easy to work with, and respectful of my home, keeping the work area tidy.
Build quality: The bars feel extremely solid and firmly anchored to the structure. I have no doubt about their ability to keep intruders out.
If you're hesitant about securing your windows, I highly recommend doing so. It was an incredibly easy experience from start to finish, and the added peace of mind is worth every penny.
