How to replace old lock?

[fsj117]

Hi, I lost the key to my garden gate and would like to replace the lock. However, I’m not sure how to remove the old lock. I’ll upload a photo of the current lock — could you please tell me what tools I need to take it off? Also, does Bunnings sell this type of lock?

Hi @fsj117,

Unfortunately, I am not confident this is going to be a simple case of remove and replace, as this looks to be a fairly old lock on a cast-iron gate. I can't say I've ever seen a lock that matches this in store.

If you have some photos showing the tongue of the lock that extends when the key is rotated, this could help to identify a replacement, but unfortunately, I am not confident we will be able to find one.

I would say this is likely one that you'd have to speak with a locksmith for assistance with. They may be able to simply replace the barrel with a new one and service the lock to ensure it is functional.

Let me know what you think.
