With the recent events of the Coronavirus and Governor Wolf issuing a statewide shutdown of non-essential businesses we are forced to have to close our doors until we are advised we may open again. We are currently offering emergency service only.  Please call 717-564-2230.

We care about the health and well-being of our clients and our employees. We ask everyone to be safe and take all precautions to avoid transmitting this virus.

1.  We're so sure of the protection you get with our security installations, that we'll pay you up to $500.00 toward your insurance deductible if you do suffer a loss from intrusion while being secured with one of our security systems.

2.  If you're unhappy with my installation or repairs, I'll gladly refund ALL your money.  I'd rather have a client who feels they were treated properly and with the utmost respect, than a mad client bad-mouthing my company to all their friends.  My business has been built on my reputation for being honest and trustworthy, and I'd rather refund your money than tarnish my image!!

You get two guarantees plus a twelve month "No Weasel Clause" and "No Hassle" guarantee (all part of our Super Strength Guarantee) - at no cost to you!  No other security company in our area is willing to back-up their installations and repairs as strongly as I am, nor will you find another security company in our area that's willing to give you the guarantees that you receive here!
Carol Shearer, President
Choosing the right security dealer is very important.  I know how difficult it can be to select a security integrator that is both knowledgeable and trustworthy.  We would like to prove to you that we are a trusted security integrator that will deliver top-notch installation and upgrades, within your budget.  And that's why I'm offering you a free 75 Point "Home-Safe-Home" Security Audit of you home, condo, apartment or other abode.

Our comprehensive security audit, that we've designed and developed here at Shearer Security will identify all the "weak spots" and safety valnerabilities on your property.  I wan to, first, identify the security problems you have and, second, demonstrate to you our knowledge and expertise.  We beleive in educatin our prospective clients so YOU can make well-informed decisions about the safety and security needs for your unique property... and that's exactly what this audit will do!  You will receive all the information needed to provide the right security system for you.

As you may already know, Wayne Shearer, Shearer Locksmith founder and owner, passed away on February 14th following a very courageous battle with cancer.     During his illness, he offered us his consulting services to help prepare for the future without him.  His guidance and wisdom could definitely not be learned in a book!  I had met Wayne 5 years after he started the locksmith business part time. He was running all the evening and weekend service calls himself all while still working full-time at TMI.  So in order to spend time with him, I jumped in the van and became his “clipboard” girl.  In 1994, he made the decision to quit TMI and proceed full-time with building the locksmith business.  After our son was born in 1995, I also began working full time handling the accounts receivable and remained by his side helping to grow the business. Now, almost 31 years later, we proudly provide a full scale of dependable, quality lock and security services reaching even beyond the Central PA area.   Customer satisfaction has been key in our growth.   So, I have now jumped over into the helm of full ownership relying heavily on our service managers, Anna and Bob, along with the rest of our team. Our goal is to provide many more years of outstanding service as we move from this generation and on to the next with our son, Nicholas, who has recently become an integral part of the business.    We thank you for your trust in us and we look forward to providing your security needs for many years to come.  Thank you also for your many condolences -  they are very much appreciated.
