Losing your house keys can happen to anyone, and in Tucson, it often comes with extra challenges. From the blazing summer heat to seasonal population changes, being locked out is more than an inconvenience. It can be a safety issue and a costly mistake if handled the wrong way. This guide will walk you through what to do immediately, how to keep your home secure, and how to prevent the situation from happening again.

Step 1: Stay Calm and Retrace Your Steps
The first thing to do is stop and think about when and where you last saw your keys. People often lose them when they are rushing, juggling groceries, or distracted by their phone. Check the obvious places first, like bags, pockets, countertops, or the area around your car. In Tucson, lost keys are sometimes found in unexpected spots, such as the patio furniture outside or left on a porch during quick errands.
If you were out running errands, consider calling the businesses you visited. Many local grocery stores and coffee shops keep lost and found logs and can hold items for several days.
Step 2: Check for a Spare Key
If you have given a spare key to a trusted friend, family member, or neighbor, reach out to them. Having a reliable spare key plan can save you from calling a locksmith in urgent situations. If you do not have one in place, it is worth making arrangements for the future. Avoid hiding keys under doormats, flowerpots, or other obvious spots, as these are the first places a potential intruder might check. A secure lockbox mounted in a discreet location is a much safer alternative.
Step 3: Avoid Forcing Your Way In
Breaking a window or prying open a door is not only unsafe but can cause hundreds of dollars in damage. Many modern Tucson homes use reinforced doors or steel security screens that are extremely difficult to bypass without proper tools. Even if you manage to get inside, you may compromise your home’s security and end up needing expensive repairs.
Step 4: Call a Reputable Local Locksmith
If you cannot access your spare or the keys are truly gone, it is time to call a professional. A good locksmith will get you back inside without damaging your locks and can also help you take additional steps to protect your home.
On Call Locksmith is a trusted option for Tucson residents. We operate 24 hours a day, seven days a week, and can usually arrive within 20 to 30 minutes. Their technicians are equipped for both traditional lockouts and more complex situations, such as high-security locks or smart lock systems. Because they are based locally, they know Tucson’s neighborhoods and traffic patterns, which helps reduce wait times.
Step 5: Consider Rekeying or Replacing Your Locks
If you believe your keys were stolen or lost along with anything that could identify your address, you should rekey or replace your locks as soon as possible. Rekeying changes the internal mechanism of the lock so that the old key no longer works, which is often faster and more affordable than replacing the lock entirely.
On Call Locksmith offers both services on-site, meaning you can regain access and secure your home in one visit. This step is not just for peace of mind. According to the FBI, over 1.4 million residential burglaries occur each year in the United States, and compromised keys can make your home an easier target.
Step 6: Take Preventative Measures
Once the immediate situation is resolved, think about how to prevent future lockouts. Here are a few options that work well in Tucson’s climate and living conditions:
Smart locks that use a code, smartphone app, or fingerprint scanner instead of a physical key.
Lockboxes mounted in a shaded and discreet location to store an emergency key.
Key trackers like an Apple AirTag or Tile, which can help you find misplaced keys quickly.
Regular lock maintenance, especially in the desert climate where dust and heat can cause wear over time.
If you live in a student-heavy area like around the University of Arizona, or in a neighborhood with a lot of rental turnover, you may want to change or rekey your locks more often as a precaution.
Step 7: Create a Tucson Lockout Action Plan
Here is a simple framework you can follow if you ever lose your keys again:
Pause and retrace your steps.
Check with family, roommates, or neighbors for a spare.
Avoid forcing entry.
Call a reputable locksmith like On Call Locksmith (hey, that's us!) for assistance.
Rekey or replace locks if keys are stolen or cannot be recovered.
Put preventative measures in place to reduce the chance of it happening again.
Being locked out of your home in Tucson is never pleasant, but it does not have to be a disaster. By staying calm, knowing who to call, and taking steps to secure your property, you can handle the situation quickly and avoid future problems. Keep the number for a trusted local locksmith like On Call Locksmith saved in your phone. That way, if you ever find yourself standing outside in the heat without your keys, you will know help is on the way.
