Car Key Checklist Before Holiday Travel This Thanksgiving

The best time to sort out your car keys is the week before a holiday trip, while you are still at home with options. A short car key checklist before holiday travel means testing your fob, counting your working keys, getting a spare made if you only have one and knowing what to have ready if a key goes missing hundreds of miles from Silver Spring.

Thanksgiving falls on November 26 this year, and the roads around the DMV get crowded well before that. Here is what to check, in the order we would check it.

Why the week before the trip matters

Holiday travel is heavy on driving. For Thanksgiving 2025, AAA projected that 81.8 million people would travel at least 50 miles from home and that at least 73 million of them would go by car, according to the AAA newsroom. AAA also reported nearly 600,000 roadside assistance calls over the previous Thanksgiving period, with dead batteries and flat tires among the usual causes.

A lost or failing key is a different kind of problem. If your only key is a push-to-start fob and it disappears at a rest stop or a relative’s house, the car usually stays put until a new key is cut and programmed to it. Doing that at home, on a weekday, with your paperwork in the drawer, is far easier than doing it on the road.

Timing matters too. Master Locksmith works Monday through Saturday, 7am to 11pm, and Sunday, 8am to 6pm, so if you find a problem late in the week, call early in the day.

Your car key checklist before holiday travel

1. Count the keys that actually work

Many households think they have two keys when they really have one. The second fob is in a kitchen drawer with a dead battery, or it belonged to a previous owner and was never programmed to the car. Take every key you have out to the car and test each one: lock the doors, open them again, pop the trunk and start the engine.

If only one key passes every test, you have a single point of failure going into a long drive.

2. Check the fob battery and the hidden key blade

A fob that needs to be closer to the car than it used to, or that works on the second press instead of the first, is often running low on battery. Cold mornings make a weak battery more obvious. Your owner’s manual shows the battery type and how to open the case.

Most smart fobs also hide a mechanical key blade inside. Slide it out and make sure you know where the matching keyhole is on the driver’s door, since some are hidden under a small cap on the handle. If the fob dies completely, that blade is how you get back in.

3. Get a spare key made before you leave

If you only have one working key, this is the item that matters most. A spare made now is a short appointment. A replacement made after the only key is lost usually takes more steps, because nothing is left to copy from.

Our technicians come to your vehicle in a service van and cut and program keys and fobs on site for most domestic and foreign makes. What is possible depends on the make, model and year, so we confirm that on the phone and give you a clear quote and an honest ETA before anyone is sent. See our car key duplicate service for the details.

4. Decide who carries the spare

A spare only helps if it is somewhere you can reach. Two common setups work well on a road trip:

• Two drivers in the car each keep a key on them, in different pockets or bags.
• One key travels with you and the spare stays with someone at home who can get it to you if needed.

Avoid keeping the spare inside the car. If the car is stolen or you lock the only other key inside, the spare goes with it.

5. Have your ownership details ready

A reputable locksmith will verify that you own the vehicle, or are authorized to use it, before opening it or making a key. That protects you as much as anyone. Before you leave, take a few minutes to:

• Photograph your vehicle registration and keep the original where your car’s paperwork normally lives.
• Note the make, model, year and VIN. The VIN is printed on a plate at the base of the windshield on the driver’s side and on your registration.
• Make sure the name on the registration matches the ID of whoever will be dealing with a lost key, or that they have the owner’s go-ahead.

6. Protect a push-to-start car while it is parked

Montgomery County police have pointed to key fob vehicles as a current theft trend, with devices that pick up a nearby fob’s signal used to open them, as MyMCMedia reported. Holiday trips mean nights parked in unfamiliar driveways, hotel lots and garages.

Keep fobs well away from doors and windows at night, and consider a signal-blocking pouch for keys you are not using. Montgomery County police also offer steering wheel locks at district stations. Our post on key fob car theft in Montgomery County covers more of the habits that help.

7. Plan for airport parking and handoffs

If you are flying from BWI or Reagan National and leaving the car, keep the key on you rather than in a jacket you might check or leave behind. If a family member is dropping you off and taking the car home, hand over the spare before you leave, not the only key. Our guide to car lockouts at BWI or Reagan National walks through what to do if it goes wrong at the airport.

If a key goes missing during the trip

Retrace your steps first. Check the seat gaps and every coat pocket, then call the places you stopped before assuming the key is gone for good.

If the key is truly lost, lock the car if you can and make sure it is parked somewhere it will not be towed or ticketed while you sort it out. If a child or pet is ever locked inside a car, call 911 first.

When you are back in our service area, or if the car is stranded within it, call us with the make, model and year ready. We explain the choices before any work starts. If you think someone could match the lost key to your car, mention it on the call so we can explain your options.

Common questions before a road trip

Can a locksmith make a car key without the original?

Often, yes. For many vehicles a new key can be cut and programmed using the vehicle’s details and proof of ownership. It depends on the make, model and year, which is why we ask for them on the first call. Our key and fob programming page explains more.

Do I need to bring the car to you?

No. We are a mobile locksmith, so a technician comes to where the car is parked in our service area, from a Silver Spring driveway to a garage in DC.
