Before you tear the house apart or start canceling anything, search in the right order.
Most keys turn up in the first hour, and usually somewhere you already looked once.
Search in this order
Retrace your last 2–3 stops. The car, the front door, wherever you set your bag or coat down. Most lost keys are within a few feet of one of these, not randomly scattered around the house.
Check pockets and bag linings, not just surfaces. Coat pockets, the bottom of a bag, a jacket you wore yesterday. Keys hide in fabric far more than they hide in plain sight.
If you have a Tile or AirTag on them, check the app now. Even if they're out of your phone's Bluetooth range, the crowdsourced finder network can often show a last-seen location from someone else's nearby device.
Ask whoever saw you last. A partner, roommate, or coworker will sometimes have moved them without thinking to mention it.
Don't rush to replace or re-key. If there's any chance they're still in the house or car, an expensive same-day dealer replacement or a full re-key can turn out to be money you didn't need to spend.
The part most advice skips
Trackers only help if they were already there. A Tile or AirTag attached before the keys went missing is genuinely useful. Buying one after the fact doesn't help this time, only next time.
The first hour matters most. The odds of finding keys through your own memory and a systematic search drop fast after that. If an hour of searching hasn't worked, it's reasonable to start thinking about backups.
A lost house key is cheap. A lost car key usually isn't. A basic cut key is a few dollars. A modern chipped or push-to-start fob is a $150–$400+ job, and a locksmith is often meaningfully cheaper than a dealer for the same result.
Re-keying is a judgment call, not a reflex. If a stranger might have them, change the locks. If they're almost certainly still yours to find, it's fine to search a bit longer first.
If it's your only set
Check for a hidden spare before calling anyone; more households have one than remember having one. If there's truly no spare, a locksmith can usually get you back into your house same-day for less than an emergency dealer callout for a car key.
If you think they're gone for good
For a car key: call around, a locksmith quote and a dealer quote can differ by hundreds of dollars for the identical fob. For house keys: re-key rather than replace every lock outright, it's the same security for a fraction of the cost.

Quick answers
How do I find my lost keys?
Retrace your last 2–3 stops before searching randomly, and check coat pockets and bag linings, not just tables and counters. Most keys turn up within the first hour, in the last place you'd think to check.
What should I do if I lost my car keys?
Check for a spare before calling anyone. With no spare, a dealer or locksmith can cut and program a replacement, often cheaper through a locksmith. Roadside assistance can sometimes help in the meantime.
Can a Bluetooth tracker help me find lost keys?
Yes, if it was already attached before they went missing. Tile and AirTag both use a crowdsourced network of other people's phones to help locate a tagged item outside your own Bluetooth range.
How much does it cost to replace lost keys?
A basic house key is a few dollars. A modern car key with a chip or push-to-start fob usually runs $150–$400 at a dealer, sometimes more for luxury models; a locksmith is often cheaper for the same job.
Should I re-key my locks if I lost my house keys?
If a stranger might have them, yes. If they're almost certainly still in your house or car, it's reasonable to keep searching a bit longer first.
One place keys disappear for good
Most lost keys turn up. Washed keys don't come back the same way.
A misplaced key fob is usually a search problem. A washed key fob, wallet, or set of AirPods is a different problem entirely, detergent, heat, and a 40-minute spin cycle don't care how important it is. If your fob or cards actually went through a wash, not just missing, see the
key fob rescue guide or the wallet rescue guide.
WashDog is built for that exact moment. It's a small device that watches your washer and catches tagged valuables before the cycle starts. It won't help you find keys left at a restaurant, but it can make sure they never end up spinning in the wash in the first place.
