I have had a customer in Aveley who has had a composite door fitted. On 2 occasions she has left the key on the inside which prevents the key on the outside working this has cost her £50 each time. I advised her to have a key and turn cylinder fitted this has a knob on the inside so she cannot leave the key inside all so if there is a fire she is not searching for keys in a smoke filled house and if she has a fall a relative with a key will still be able to get in.
This takes around 10 minutes to change and she has the peace of mind of knowing she will not be locked out again
