RV Wheel Chock Guide: Sizes, Types, and Proper Placement

By the SecurityMan Security Team | Last updated: February 2026 | About SecurityMan

Whether you are staying in a hotel, Airbnb, or temporary housing, the security of an unfamiliar room is never certain. According to a SafeWise survey, 27% of Americans have had items stolen from a hotel room. The locks on hotel and rental doors vary widely in quality, and you have no way to know who else has a key to your room.

This guide covers portable, proven security measures you can carry in a bag and set up in any room in under two minutes.

Why Hotel and Rental Security Is Different

When you stay somewhere temporarily, you face a specific set of risks that do not apply to your own home. Previous guests, staff members, and maintenance workers may have keys or access codes to your room. Electronic key cards can be duplicated. And you are sleeping in an unfamiliar environment where you do not know the layout, escape routes, or neighborhood.

The Bureau of Justice Statistics reports that homes left unoccupied for extended periods are 2x more likely to be burglarized. While this statistic refers to your home while you travel, the same principle of vulnerability applies to the temporary space you are sleeping in.

Pack These Three Things

1. A Portable Door Security Bar

The 3-in-1 Door Security Bar collapses for travel and extends to brace between the floor and door handle of most standard hotel doors. Even if someone has a key card, the bar prevents the door from opening. It takes three seconds to set up and weighs about 2 pounds, fitting easily in a suitcase.

2. A Door Wedge Alarm

The Door Stop Alarm Wedge (2-Pack) is the most travel-friendly security device available. It weighs a few ounces, fits in a jacket pocket, and provides both a physical barrier and a 120dB alarm. Slide it under the door before bed. If anyone tries to enter, the wedge holds the door while the alarm wakes you and alerts nearby rooms.

3. A Personal Alarm

A 130dB personal alarm on your keychain provides security outside the room as well. Walking to your car in an unfamiliar parking garage, exploring a new neighborhood after dark, or riding public transit in an unknown city all carry some risk. A personal alarm draws immediate attention, which is the most effective self-defense tool in most situations.

Room Security Checklist

When you arrive at any temporary accommodation, do a quick security check: verify the door lock and deadbolt function properly, check that the peephole works (and is not reversed), confirm windows and sliding doors lock, look for connecting doors to adjacent rooms and ensure they are locked from your side, and note the location of the nearest exit.

Airbnb and Vacation Rental Specifics

Vacation rentals present unique concerns. Smart locks may store entry codes from previous guests. Security cameras (both disclosed and undisclosed) are a documented concern. Check the listing for camera disclosures, inspect the property on arrival for hidden cameras in bedrooms and bathrooms, and change any entry codes if the lock system allows it.

Protecting Your Home While You Travel

Your home is also at risk while you are away. Use smart plugs on timers for lights, pause mail and package deliveries, ask a neighbor to check on the property, and set up your door security bar and wedge alarm on entry doors before you leave. Contrary to popular belief, 65% of residential burglaries happen between 6 AM and 6 PM when homes are more likely to be empty (Bureau of Justice Statistics). Maintaining the appearance of occupancy is the most effective deterrent.

The Layered Security Approach (And Why It Matters)

Security professionals talk about "defense in depth" or the "layered approach." The concept is simple: no single security measure is unbeatable, but multiple layers working together create a cumulative effect that makes your home far too difficult and risky for a burglar to target.

Think of it in four layers. Layer one is deterrence: visible security devices, good lighting, and signs of occupancy. Layer two is detection: alarms, cameras, and motion sensors that alert you to a breach. Layer three is delay: physical barriers like locks, security bars, and reinforced frames that slow down entry. Layer four is response: your plan for what happens when layers one through three are tested.

The average burglar spends fewer than 10 minutes inside a home. If your layers of deterrence, detection, and delay consume even 3-5 minutes of that time at the entry point, many burglars will abandon the attempt entirely. Research from the University of North Carolina at Charlotte confirms this: about 60% of convicted burglars said they would seek another target if they encountered unexpected security measures.

This is why a combination of a security bar (delay), a door alarm (detection), and visible security presence (deterrence) is far more effective than any single expensive lock. Each layer covers the weaknesses of the others, and the cumulative effect is what makes your home a difficult target.

Seasonal Security Considerations

Your security needs shift throughout the year. Being aware of these patterns helps you stay protected during higher-risk periods.

Summer. Burglary rates peak during summer months, particularly July and August. Longer daylight hours mean more time for daytime burglaries (when most homes are empty), and vacation travel leaves homes unoccupied for extended periods. This is the most important time to deploy all your security measures and use timers and deterrents while away.

Holiday season (November-December). Visible gifts near windows, delivery packages on porches, and homes left empty for family travel create a second peak in property crime. Move gifts away from windows, schedule package deliveries to arrive when you are home, and use all your security devices during holiday travel.

Back to school (August-September). Students moving into apartments and dorms create a spike in property crime in college towns. New residents are less familiar with their neighborhood, doors are often left open during move-in, and new electronics are abundant. If you are moving into a new place during this period, set up your security measures on day one.

Spring. As weather warms up, people open windows more frequently and forget to lock them before bed or when leaving. Spring is also when construction and maintenance workers are more active in neighborhoods, making it easier for someone to blend in while casing homes. Keep windows locked when you are not in the room, even during pleasant weather.

Frequently Asked Questions

What is the best portable door lock for travel?

A door wedge alarm is the most portable option (pocket-sized, a few ounces) and provides both physical resistance and an alarm. For more robust protection, a collapsible door security bar fits in a suitcase and physically prevents the door from opening.

Can someone enter my hotel room with a master key while I sleep?

Yes, hotel staff, maintenance, and management typically have master key access. A door security bar or wedge alarm prevents entry regardless of who has a key, giving you control over your room security while you sleep.

Are Airbnb vacation rentals safe?

Most are, but security varies widely. Always check reviews, inspect locks on arrival, look for undisclosed cameras, and bring portable security devices. Your security should never depend entirely on a stranger's property.

How do I secure a hotel room door?

Use a door wedge alarm under the door and a portable security bar against the handle. Engage the deadbolt and any secondary lock (chain or flip guard). Check that the connecting door to adjacent rooms is locked from your side.
