Our Company

Our Story

Markle Security Services was founded as a small locksmith business in 1948 by Luther Markle in his home garage. In the years since then, we have grown into two storefronts and have a small fleet of mobile vehicles. We have also expanded our offerings to include security services, vault services, and lock service and replacement. Today, our business is still family-owned and operated by Luther’s great-grandson Zach, who continues the family tradition of providing PA with the highest quality products and services.

Case Study

We installed a camera security system at a local eating establishment to help secure their property, employees and customers for both the internal space and exterior perimeter.

One evening a car was stolen out of the parking lot and our team was called on to review video footage help identify the perpetrator who committed the crime.

Due to perfect camera placement and excellent image resolution, we were able to easily identify the suspect and after notifying the authorities, the thief was taken into custody.

Thanks for the prompt service.

Very happy to say that one of your employees helped my family out tremendously this past weekend after hours when our garage door failed to work and we had locked all the doors without a key.
