1. Open locks
Frosty mornings can catch drivers off guard, especially when a car sits unused on very cold days. The initial struggle often begins at the approach, as lock cylinders may freeze and keys refuse to turn. To minimize this, keep keys warm in inner pockets and consider carrying a spare.
Manual door entry can be stubborn when locks freeze. The simplest remedy is to have a small defroster or a lighter handy to warm the key tip. A practical trick is to blow into the lock through a straw, then apply a lubricant like WD-40 to the cylinder to prevent moisture from warming and sticking again.
2. On the way in
A frozen door seal can block entry by freezing along the frame. Try pulling gently on all doors, occasionally yielding a little more movement as the metal and plastic warm slightly.
Avoid using brute force; door handles are usually plastic and can crack under heavy pressure in cold weather. Instead, push the door as if guiding it into its opening, starting with the window frame, which tends to freeze first.
If obstacles persist, apply a glass defroster so its nozzle reaches the door slot, or use slightly warmed antifreeze fluid retrieved from home or a store. The key is to keep the liquid warm enough to help melt the ice without harming rubber seals.
For hatchbacks and station wagons, entering through the tailgate is a viable option. Start the engine to warm the interior, or attempt to open the door from the inside.
Applying silicone grease to all seals at the start of winter helps prevent sticking and is worth refreshing periodically throughout the season.
3. Start the engine safely
Before ignition, ensure the windshield wiper switch is off to protect the wiper mechanism, which can suffer if frozen to the glass.
Avoid unnecessary battery drain by not activating headlights while the engine is still warming. If the engine does not start after a few cranks, do not rush to release the key. The starter is capable of rotating the crankshaft for up to ten seconds without harm.
Three attempts spaced at least thirty seconds apart are permissible. If the engine still won’t start, conserve the battery and inspect for a fault.
Immediately after starting, verify that the oil pressure warning light goes out. If it remains lit, stop the engine promptly to prevent damage. An oil pressure warning that remains active after start is a serious signal that requires attention.
4. Defrost glass
Windshields can be iced on the exterior and frosted on the interior. Right after starting, direct the heater’s airflow to the glass and run the fan on a low setting.
Remember to activate heated mirrors and windows if the vehicle is equipped. Clear ice from the windshield wipers as needed.
When in a rush, use a plastic scraper for the exterior surface and a plastic card to thaw interior frost.
Even if some frost remains, the dashboard may appear dimmed by the moment, signaling it’s time to finish the defrost cycle.
