For many drivers across the UK, a frosty morning brings a familiar and frustrating struggle: car doors that are frozen solid and refuse to open. This common winter headache can waste precious minutes as motorists try to warm or force their doors open.
The Simple £3 Solution to Prevent Frozen Locks
Experts, however, advise that this problem is largely avoidable with a little preparation and a very inexpensive product. The key is a water-resistant silicone spray lubricant, which can be purchased online or in shops for as little as £3.
Applying this spray to door seals and lock mechanisms creates a protective barrier that repels moisture, stopping ice from forming in the first place. Ali Lijee, CEO at myWindscreen, explains the science behind the issue: "Most people assume frozen locks are just bad luck, but it’s actually a very predictable chain reaction."
How Moisture and Cold Cause the Problem
"Moisture gets into tiny gaps around the lock barrel or inside the rubber door seals," Ali states. "Once temperatures drop overnight, that moisture freezes and suddenly nothing moves." This simple process is what leaves drivers wrestling with their vehicles on cold days.
He emphasises that prevention is straightforward: "The most effective thing you can do is treat your locks and seals in advance using a water-resistant silicone lubricant. It creates a barrier that stops moisture sticking in the first place."
Applying the Lubricant Correctly for Best Results
Not all sprays are suitable for this task. Ali highlights that a silicone lubricant is specifically designed to repel water and remain flexible in sub-zero conditions, which is crucial for winter effectiveness.
For vehicles that still use a traditional physical key, he recommends a specific method:
- Ensure the product is labelled as water-resistant silicone and safe for metal components.
- Use the thin straw nozzle to insert into the keyhole and give a very short spray – around two seconds is sufficient.
- To spread the lubricant inside the mechanism, slide the key in and out several times.
- Finally, wipe away any excess spray around the exterior of the lock to prevent it from attracting dirt.
By taking these simple steps before the coldest weather sets in, drivers can save themselves significant time and hassle, ensuring their car doors open smoothly no matter how low the temperature drops.
