fwiw molgrips …. you may find your door has the weakness that most low priced electric doors have.
a lot of electric doors are not as secure as you think for the most part – especially the ones you find on most modern mass built houses from the big developers. you can pay a good chunk more and get a much more secure one but as you know – if you did that you’d have no other way in. id always suggest a pair of side bolts at the bottom if you keep anything of value in.
amazing what you find out working on building sites and needing power – watching a worky open an electric door with a brush with a nail on it (and not damaging) it because the siteforeman isn’t there yet is an eye opener.
