Quick answer: The best low-cost car anti-theft setup under $50 is usually a visible deterrent, key signal protection if you have a push-button-start vehicle, and at least one recovery aid. A steering wheel lock, Faraday pouch, OBD port lock, or hidden tracker can each help in different situations, but none should be treated as theft-proof on its own.
Are you worried about car theft, but money’s a bit too tight to drop thousands on state-of-the-art alarm systems, immobilizers, trackers, and all the other fancy gadgets? Don’t worry, we got you! Here is a list of devices that will get you the most bang for your buck, and typically cost less than 50 bucks. So you can build your layered anti-theft protection plan one affordable piece at a time.
The Club Twin Hooks
When on a budget, a steering wheel lock is probably your best first purchase for automotive security. They add an extra step thieves have to take and act as an excellent visual deterrent that may even save your window from being broken. This model is a good, affordable choice that is still sturdy and bright yellow colored so potential thieves will see it easily. While clubs can be fairly easily defeated by a determined thief with the right tools, no device is truly impossible to bypass, and these can be very effective for the small investment.

The Club Pedal to Steering Wheel Lock
Using a pedal lock is another affordable measure you can take to make your car harder to steal. This product is similar to a steering wheel lock, but is intended to hook around your brake or clutch pedal and your steering wheel to prevent the pedal from being pressed. A traditional steering wheel lock is preferred over this type due to it’s higher visibility for deterrence and ease of use, but using both devices together will provide increased protection.

Apple AirTag
AirTags may not be the perfect choice for a vehicle tracker, mainly because of their anti-stalking features. But they are very affordable, require no subscription, are small enough to hide almost anywhere, and are way better than not having any means to track your car if it’s stolen. While it’s certainly best to focus on the prevention of theft, having a “Plan B” if things go wrong is very important too. (See our full article on tracking devices here)
Kill Switches
When done correctly and hidden well enough, kill switches can be one of the cheapest and most effective theft prevention options out there. The biggest downside is that they take some experience to install correctly, so this is not a DIY project for everyone. The option we listed here is a good example of a switch you can use, but there are lots of good different options out there, and please be sure to choose a switch that will work well with your vehicle and the system you intend to disable. Placement is absolutely critical, as is remembering to use it, as the kill switch will be useless if it is easily found by a thief, or you forget to use it. (See more about kill switches here)
Faraday Pouch
Faraday pouches are another very effective and affordable way to protect your car against theft. But only if you drive a car with push-button-start technology (proximity keys). This is because faraday pouches block the signal that your key emits that thieves commonly clone in relay attack thefts. While they may not protect against all types of theft, faraday pouches are good, cheap insurance for a type of theft that is used very frequently to steal cars with this technology, and can reduce your risk of theft greatly. Again, if you have a regular key you twist in your ignition, this is not necessary, but if you have push-to-start these pouches are very important. (See our full article on faraday pouches)
OBD Port Lock
OBD port locks are another good option for owners of vehicles equipped with push-button-start proximity keys, they can also be an added layer of security for any vehicle with chipped security keys but are not quite as important for these cars. These devices combat methods of theft where thieves plug devices into your car’s OBD-II port to either make new keys or force-start the car by physically blocking the port they plug into. (See our full article on OBD port locks here)
Remote Battery Disconnect
Remote battery disconnects are an inexpensive type of immobilizer for your vehicle that are also simple to install with basic tools. They are installed between the battery and cables to allow you to disable to the vehicle with the touch of a button on the included remote. While they do add a significant amount of protection against theft when used properly, they come with the drawback of your car acting like it had a dead battery after every use. For example, your clock and other features may reset, windows may not work right until they undergo the “normalizing” procedure, readiness monitors will reset, etc. Also, any security features that require battery (like alarms) will not work when this device is in use. (See our full article on remote battery disconnects here)
Driveway Alarm
Driveway motion sensing alarms are a great way to know if someone is coming down your driveway late at night. The sensor will send the alarm to a speaker inside your house, giving you an early alert that someone is there which is not only good for your vehicle’s security, but yours as well. (See our full article on Driveway Alarms here)
Ring Wired Doorbell Camera
If you’re looking for a good driveway facing camera that doesn’t break the bank, the Ring Wired Doorbell Camera is a good place to start, especially if your front door has a good view of where you park your car. Even though it is a wired setup, installation is not very difficult when replacing an existing doorbell, and Ring does a good job of making instructions easy to understand. Basic use of the camera does not require a subscription, but one will be needed for certain features like saving video. (See our full article on Home Security Cameras here)
Neutral Strap Cover (Charger/Challenger)
View on Amazon (Charger)
View on Amazon (Challenger)
Dodge Chargers and Challengers are very common targets for theft. Oftentimes when a thief cannot start the car quickly enough, they pull the neutral release strap that is located next to your shifter so that the wheels will spin freely and they can push it (usually with another vehicle) somewhere nearby where they can have more time to make a new key or force start the car.
