Lost patio door key

[pop1973]

I have lost the patio door key to a large patio door.

Does anyone know how much it will cost to get a locksmith out to replace the key.

It is a rented house and this is the only key to the door. We don't want to loose our bond when we leave shortly.

Any ideas of cost ??

Does the landlord not have a spare you can copy?

Is the door locked right now? If the landlord doesn't have a copy and you can open it, I would just replace the lock for a new one.

Hi

No he doesn't have a spare key otherwise we would have got it from him.
The door is locked right now, so we can't open it.
