"Nathan showed up on time on the same Saturday that I called, for rekeying the security door bolt lock, since we had lost one set of keys. He advised me to rekey the deadbolt on the inner, stouter door, and charged only slightly more. Excellent service!"

"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!"

"Darrin fixed an increasingly problematic front door mortise lock. Works swell now; it was a toughie. He also fixed two other outside door locks that had been iffy. Prior repairman who had installed the locks and doors didn't do a great job. Now we have working and locking doors. Spiffy. I thought the price was very reasonable. He was professional and knowledgeable. Will hire him again for any lock issues. I wish I had done this over a year ago instead of dreading it (afraid we would have to replace the locks or doors)."

"DO NOT USE THEM!!! First they required a credit card to come out then they came out and spent an hour attempting to rekey my lock but couldn't then charged me $150 for doing nothing because they claim the lock was damaged. They gave me a quote to replace the Anderson lock for an absurd amount like thousands of dollars. Then I had another locksmith replace the cylinder in less than an hour and it was all done. I requested a refund and they refused so I disputed with my credit card and Reeds had the audacity to call me to tell me llied and asked me if how I could sleep at night. I asked him how he could sleep at night because I told the truth and they tried to scam me. They are highly unethical!"

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.
