"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

"Great work from Daniel and his team. Innovation Painting took care of our home in San Francisco. Prompt, friendly, and great attention to detail. After they were done painting, Daniel walked me around the property to go over things they uncovered while painting, like suggested repairs, which I very much appreciated. I would absolutely recommend Innovation Painting. Thanks!"

"When I called Prolocksmith I got a dispatch person who seemed to be working from home. She was quick in trying to connect me with someone to do the work. Referred me to discuss rate and other specifics with the locksmith who would be performing the work. The actual locksmith called me within 5 minutes and indicated that he would be at my place in 20 minutes. I had to interrupt him to tell him what type of lock was on my door. Also when I asked about rates, he said that he would not be able to tell until he was there and I could opt out at that time. Locksmith who showed up was with another company and did not know anything about Angieslist. He tried to give me some sort of a discount but said the software on his smartphone would not let him. Upside, he arrived within 30 minutes. Downside, cost $272 and I am not sure what company opened my door but it was not the licensed Prolocksmiths."

FAQs for locksmith service projects in San Francisco, CA

The installation timeframe varies based on door preparation and lock complexity. For doors already prepared with appropriate holes, installation might take 15 to 30 minutes. New installations requiring drilling take one to two hours. First-time DIY installers should allocate additional time to ensure proper alignment and function. Professional locksmiths complete standard installations efficiently due to their specialized tools and experience.

Most residential doors can accommodate deadbolts, but certain door types present challenges. Solid wood and fiberglass doors accept standard deadbolt hardware, while metal doors require specialized drilling equipment. Hollow-core interior doors lack the structural integrity to properly support deadbolts without additional reinforcement. Doors should be at least 1⅜ inches thick to properly house standard deadbolt mechanisms.

Door warranties remain valid when deadbolts are installed according to the manufacturer's guidelines. However, improper installation that damages the door structure might affect warranty coverage. 

Before modifying any door under warranty, review the documentation for specific limitations or requirements regarding hardware installation. Some manufacturers provide templates or guidelines for acceptable lock placement to maintain warranty protection.

Rekeying offers a more economical alternative to complete replacement when you need to change access, but the lock mechanism remains in good condition. This process involves reconfiguring the internal pins to work with a new key while retaining the existing hardware. For homeowners with multiple locks, rekeying provides the convenience of using a single key for all entry points while maintaining security.
