Keeping Your Car Safe: A Practical Guide To Preventing Vehicle Theft

Let’s face it, motor vehicle theft is on the rise. Modern cars come with clever tech to keep them secure but thieves are getting smarter too. The good news is that you can take plenty of simple steps you can take to stay one step ahead and protect your pride and joy.
Lock it or lose it
Always double-check your car is locked even if you have it parked on your driveaway or at the petrol station. As well as ensuring sure all windows and sunroofs are closed because an open window is all it takes. Don’t give opportunist thieves a helping hand.
In colder months, it’s tempting to leave your engine running to defrost the windscreen or warm the car up. It’s illegal to leave a vehicle unattended with the engine running. Worse still, if someone steals it while you are inside enjoying a brew, your insurer will not pay out.
A quick tip for cars with automatic folding wing mirrors. If they aren’t folded in, it’s a clear sign the vehicle is not locked. Professional criminals know this and often use it to their advantage.
Keep your keys close, but not too close
Most modern cars are tough to steal without the key or fob, so keep yours safe. At home, don’t leave the keys in plain sight or anywhere near the front door. Some thieves still use rods and hooks through the letterbox to go fishing for them. Yes, unbelievable but true.
If you are meeting someone to sell your car, never let the keys out of your sight. Criminals sometimes use these opportunities to clone your key and return later to steal the vehicle.
Keyless entry, a handful feature but also a risk
If your car unlocks just by you being nearby, it probably has keyless entry. It’s convenient but it also opens the door (pardon the pun) to relay theft. Thieves can use special devices to mimic your key’s signal, even from inside your home. They can then unlock and start your car in seconds.
To protect your keyless car, keep the fob well away from doors and windows. Store it in a Faraday pouch, which blocks the signal. These don’t last forever, so it’s worth checking that yours still works. If you’ve bought a second-hand car, consider reprogramming the keys. Where possible, switch off the wireless signal when you don’t need it.
Carjackers are not just in action films
Unfortunately, having your car stolen while you’re inside is possible. It’s rare, but it does happen. Stay alert, especially in traffic. Keep your doors locked and leave enough space between you and the car in front. If you need to make a quick getaway, you’ll be glad you did. This adds car theft protection.
If you are nudged from behind, don’t stop immediately unless you are somewhere busy and well-lit. It could be a tactic to get you out of the car. If you are suspicious, call the police before stepping out.
Where you park matters
Dark, quiet streets might seem convenient but they are also ideal for thieves. If you can, choose a well-lit, busy area. Look for car parks with staff or Park Mark accreditation, which shows it is safer parking. A slightly longer walk could make all the difference.
Tow truck troublemakers
Some thieves will go so far as to tow your car away. If you see a tow truck that doesn’t look right, perhaps no branding or no uniforms, trust your gut and report it. You won’t get into trouble for raising a false alarm if you act in good faith.
Car parks with height restrictions help deter this type of theft. Consider investing in an alarm system with tracking, immobilisation and movement sensors. Look for ones approved by Thatcham or Sold Secure.
Physical locks can still prevent car theft
Old-school security like steering wheel locks, gear stick locks and pedal boxes are still incredibly effective, although some are better than others. Combine them with a professionally installed immobiliser for an extra layer of protection. You ca set this up so only you know the exact steps to deactivate them. Very mission impossible but if it works who cares?
Make sure it’s locked, really locked
Sometimes devices can jam the signal from your fob, making you think you’ve locked the car when you haven’t. It’s always worth checking manually before walking away. A quick glance to see if the indicators flashed or the mirrors folded in can save you a lot of stress.
If something feels off, such as someone loitering nearby, trust your instincts and be extra cautious.
Watch out for cloned cars
Vehicle cloning happens when criminals steal a number plate from a similar make and model. They then use it on another car. Sometimes even changing the identity of a stolen vehicle.
If you are buying second-hand, make sure the Vehicle Identification Number matches the one on the V5 document. Check more than one VIN on the vehicle and look at the engine number too. If anything feels wrong, walk away.
Secure your OBD port
Many modern cars come with an On-Board Diagnostic port. Mechanics find it useful but unfortunately so do thieves. It can give them access to the systems and in some cases, even let them start the car. A simple lockable cover will help keep it secure.
While car theft can feel like one of those “it won’t happen to me” things, a few sensible steps can massively reduce the risk. It’s all about making your car less appealing and more difficult for thieves to target with strong protection.
