Mike was such a delight to work with! We had an appointment scheduled at 4 following the closing on our new house, and he called to check in and offered to come about 45 minutes early since his was ahead of schedule for the day. Once he arrived, he was not only so kind, but he thoroughly explained details of all our options and pricing. When we agreed on what we wanted (installing a keypad lock on one door, and rekeying the other to match the locks of the new keypad) he got right to work. He explained a few issues that came up during the job regarding the previously installed locks placement and adjusted it so it wasn’t so hard to the deadbolt. He also surprised us with personalized keys for our new home! Such a sweet touch. The price was reasonable for the amount of work he did and he was generous and discounted a few areas of work. Overall would recommend Reliable Locksmith and Mile any time you need help with locks and keys!

We worked with Mike to change all the locks in our new house and he was excellent. We went from 3 different keys down to one, and added a Lockly keypad to the front door so our kids won’t lose their keys. Mike had great advice, was kind and knowledgeable, and everything looks and works great. Definitely would recommend.
Response from the owner:Thank you Claudia, We appreciate your feedback.
Excellent service. Highly recommend! Trustworthy and efficient. I’ll be using them again.

Amazing! Needed another key (fob) made for my 2024 Subaru Forester. I called Reliable Locksmith and within 10 minutes or so, Eli called back to set up an appointment. He offered to come to me! All in all, it took around 15 minutes to get a new key for my car and sooo much cheaper than the dealership quoted!
Response from the owner:Thank you Jenn!

We were in Forest Lake and stopped to pick up items quickly. When we got to the store the key fob fell out of the ignition. I called the dealer in forest lake and they recommended Reliable. It did take an hour and a half to get there from their shop through rush hour traffic, bad roads and poor drivers. He had everything he needed to replace the fob. Very knowledgeable and friendly. I would recommend them to anyone in need.
Response from the owner:Thank you John, We appreciate your feedback!

Response from the owner:Thank you John! for sharing your experience with Mike, We appreciate your business and glad we could help with your locks.
Amazing, amazing, amazing! Mike was incredible. His earlier job ran late, he called and although I was fine with service the next day he said he like to still come if I was okay with him working late! His work and craftsmanship is meticulous. We had all of our locks updated to keypads via wifi. He spent extra time making sure everything aligned and the locks move 'like butter". Highly recommend!!!
Response from the owner:Thank you Michael! We appreciate your feedback

Wonderful work and lovely, trusting person. He came up with alternative solutions when our old locks failed, picked locks that had rusted and helped me program the new keypad. The work was thorough and high quality. Each lock turned “smooth as butter.” I couldn’t have asked for a better person to trust with such an important job.

I had originally called another locksmith to help me but they never called me back or showed up. I called reliable the next morning and they responded right away and the technician was here when he said he would be. They were quick, professional, and extremely courteous. I recommend calling reliable first so you don't waste time with anyone else.

I can’t say enough good things about Eli! He’s hands down the best locksmith I’ve ever worked with. I’ve used his services twice now, and both times he went above and beyond. Most recently, my kids and I were stranded at a gas station with a problem that even the dealership couldn’t solve—but Eli figured it out quickly and got us back on the road. His professionalism, skill, and kindness made a stressful situation so much easier. I’m incredibly grateful for his help, and I’ll be recommending Eli to all of my friends and family. If you need a locksmith you can truly count on, Eli is the one!

Thank you so much Eli!
Response from the owner:Thank you Zain, Appreciate your feedback.

We couldn't open our door. I called Reliable Locksmith and Mike arrived the same day. He kept us informed about timing and when he arrived he quickly fixed the lock. The work was excellent, reasonably priced and Mike was very personable. I will definitely choose him again if I have any other locksmith needs.
Response from the owner:Thank you Sharon! We appreciate your feedback
in my opinion it is really hard to find trustworthy reliable businesses today. I used chatgpt to ask who the highest rated locksmith in my area is and it stated Reliable Locksmith was the highest rated due to technicians Mike and Eli's excellent customer service. I called them and within a few hours Mike was at my door to change out my locks and door handles. The level of customer service Mike showed from start to finish was unmatched in any business I have walked into in recent memory. He went above and beyond several times when it was not necessary as he took great pride in his work and the level of detail to make it perfect. I HIGHLY recommend them for any locksmith needs one may have and will be returning and recommending them to all my friends and family. Thank you again Mike!
Response from the owner:Thank you Steven for your kind review!

Make sure that your mailbox isn’t owned and operated by the United States Postal Service

Your first step is going to be to ensure that your mailbox is a private mailbox and not one owned by USPS. That’s because locks on private mailboxes and package lockers can be replaced by the property owner, but ones owned by USPS will need to be handled by them. No matter if you’ve lost your keys, recently moved into a new home or are having trouble with the lock, USPS mailboxes must have their locks replaced by a postal service worker or contractor.

You can tell if a mailbox is owned by the USPS because there will be a label on the device stating that it is a USPS mailbox. Or, if you’re living in an apartment complex, ask your super or property manager. They’ll be able to let you know whether you can replace the locks on your individual mailbox.

Make sure that you know what locks are compatible with your mailbox

Not all lock replacements will be compatible with all kinds of mailboxes, so it’s important to look into your specific model. Some of the most common mailbox locks include:

  • Prime-Line MP4315. This is a standard replacement lock made by the trusted mailbox lock company Prime-Line. It is compatible with a number of different mailbox manufacturers, such as those made by Florence. It comes with two replacement NA-14 keys.
  • CompX National C9100 This replacement mailbox lock is a USPS approved model that can be outfitted on community boxes with a USPS specification of USPS-L-1172C. It comes with three replacement NA-14 keys.
  • CompX National C7120 Heavy-Duty Cam. If you need extra security for your mailbox, it may be worthwhile to order the C7120 heavy-duty cam. This strong locking mechanism can be installed with C9100 or C9200 mailboxes for additional security.

Decide between weatherproof and non-weatherproof locks

If your mailbox is exposed to the elements, you’ll want a lock that won’t rust or jam. So, it will be important to choose a model that is least vulnerable to corrosion. Stainless and alloy steel are two good options for weather-resistant mailbox locks.

On the other hand, if your mailbox is located within an apartment building or in a covered area where it won’t be exposed to rain or snow, you may be able to save some money by installing a non-weatherproof lock.

Choose your security level

Many residential settings don’t require high security mailboxes because they are within an area that is not accessible to the public or aren’t at high risk of mailbox tampering. So, a basic mailbox lock replacement will be sufficient for most residential security needs.

But for commercial settings, a security upgrade might be a good idea. Commercial grade mailboxes can be designed with security features such as double-layered walls and doors. They can also benefit from sturdier mailbox locks outfitted with a heavy-duty cam.

For best results, call in the pros for mailbox lock replacement

If you want to make sure that you have the highest level of security available for your mailbox, it’s a good idea to reach out to your local locksmith. Here are a few reasons why:

  • We can safely replace your lock if you’ve lost all keys. If you’ve misplaced all of the keys, you’ll need to safely remove the existing lock to replace it with a new model. When done incorrectly, this can lead to damage to the mailbox. Our locksmiths have the tools and experience to open your mailbox without further damage.
  • We can help with key extraction and key duplication. If one of your keys is broken in the lock, you may be able to avoid lock replacement. We’ll safely extract the key and duplicate it so that you can continue to use your existing mailbox lock.
  • We’ll make sure to order the right lock for the dimensions of your mailbox. In the case that you do need a new lock, we’ll help you with ordering for your specific mailbox, security needs, and budget. We have the expert knowledge to get you the best lock at the best price.
  • We can recommend any other security upgrades that will keep your mail safe. Whether you’re having issues with the lock on the door to the vestibule where the mailboxes are or you want to upgrade the security on the perimeter gate around your outdoor mailbox cluster, Reliable Locksmith can help.
