What we don’t recommend & why

Heating the key up with a lighter or match: For obvious reasons, this can be a risky one to try. There is the risk of burning or injuring yourself as well as causing damage to the key – especially the plastic part.

Tapping the lock with a hard object: Some will try this as a way to break the ice up from within the lock. However, we don’t recommend doing this. It’s too easy to hit the lock too hard and cause damage, or even slip and damage the bodywork.

Using a hairdryer: If you have an extension cable you could give this a go. However, it can be more trouble than it’s worth as you may not be able to direct the heat well into the lock and it is not recommended to use an interior electrical appliance outside on a cold, damp day.

Hand sanitizer: This has the potential to work as it will contain alcohol which would melt the ice. But coating your key with a sanitizer isn’t really recommended, especially so if it is the gel kind. This is because it can also leave behind a residue which could attract dirt and clog the lock over time.

Grease or silicone lubricants: Similarly to the hand sanitizer way, using a thicker lubricant can cause the locking mechanisms to get clogged.

Pouring boiling water onto/into the lock: This is a common option that people try and potentially the worst! Having the mechanism change temperature from freezing to boiling in an instant can cause the metal to become weaker, especially so if you do this multiple times. In the long run, you could result in a broken lock.

Forcing the key: This is another very dangerous way to deal with a frozen lock! It goes without saying that forcing the key into the lock and activating the mechanism can cause the key to snap. This is especially a problem if the key snaps inside and you cannot get it back out.

So, what do we recommend instead?

We recommend using our releasing oil and lubricant, Transyl. Transyl is a versatile, deeply penetrating, self-spreading liquid with incredible spreading and climbing properties. Because of this, it is able to reach the most difficult of areas and tricky metal parts.

Its exceptional self-spreading qualities allow the oil to move greatly within a very small area and as it displaces moisture, will quickly and effectively unfreeze a frozen car door lock.

It is available in a variety of sizes including handy 200ml spray can with a straw attachment, allowing for a very controlled and precise application.

For more information, take a look at the Transyl product page here, or read more about its many uses here.
