"I had a bit of trouble with my molding around the doors vs how the system was designed. The tech guy hung with me for 39 minutes until it was perfect. I called customer service a couple times after that with questions that came up. The customer service team are professional and knowledgeable."

"There were many things wrong in my computer (my fault and letting grandchildren on computer) Robert was so helpful, gave me many good instructions to keep everything safe, which I have written down, feel like I have a new computer. He was so excellent and experienced, took his time and was meticulous about what needed to be done. He was a pleasure to work with and I will use this company again! Linda Disy"

"Their warranty cost and service prices are more expensive than a lot of other options. They hire out to contractors with terrible ratings and you're stuck with whomever they assign you to."

Locksmiths questions, answered by experts

Expect to pay between $50 to $200 if you hire a locksmith to change your locks. That figure includes labor and the cost of basic hardware. The cost will naturally be higher if you plan to install more expensive locks, like smart locks, and if you need a lot of them.

Homeowners can save money by replacing locks themselves. A typical rekeying kit costs about $10 to $25. The only additional cost is purchasing new house keys, and those are no more than a few dollars per key. If you want to replace the locks on your own completely, the main cost is the price of the locks themselves. A standard knob-style lock starts around $25, while electronic locks and smart locks will run in the hundreds of dollars. The only additional tools you should need are a tape measure, screwdriver, and screws if they are not already provided.

There are several ways to add security to a sliding glass door. To start, install a rod or deadbolt lock instead of the flip-lock that comes standard with most sliding glass doors. Add a sensor to the door and monitor any activity through your home security system.

Finally, installing shatterproof window film will help keep the structural integrity of the glass if it cracks.

Rekeying your own locks is a low-cost task that prevents you from having to replace the locks themselves completely. The first couple of times you rekey a lock may be challenging because this is an intermediate DIY task. You can purchase a rekey kit from most hardware stores, but make sure you’re buying the kit from the brand of lock in your home that you’re going to rekey. 

Over time, latch components may wear out or get grimy, leading to this problem. First, check for dirt, dust, or debris in the latch mechanism to ensure smooth operation. Use an aerosol duster and lubricant to clean and loosen. You may also need to tighten the screws in the component, adjust the strike plate, or replace the lock. If none of these steps resolve the problem, consult a professional locksmith.

Lubricating a door lock is an important part of door lock maintenance. It involves taking the lubricant of your choice (it’s best to use whatever the lock’s manufacturer suggests) and spraying it directly into the keyway. Push and pull your key in and out of the lock to make sure it’s all the way in.
