I need to seal my attic door completely but not my using locks or bolts.I need something strong to seal it.Any idea?

There could be several causes for your issues.
If you have a FIOS box in the garage make sure that it is closed and sealed.
Make sure that there is on coax cable close to the garage door opener motor in the attic.
Could be a neighbor installed something that is causing you to loose distance.

hi best way round that is too get some strong string ..put round door were lock is and pull hard so it will undo the door ..u then need to change door lock ..its behind rubber door seal held in with x2 screws..

My new freezer did the same thing. I contacted the company and they went into the whole leveling thing. What it has to do with is the magnetic seal. The magnets are not strong enough to keep the freezer door from popping open when closing the big fridge door. They share the same duct. I level my doors on the fridge and freezer so they swing shut by themselves after opening. Just the force of the big door when it swung closed cracked open the freezer door about a quarter of an inch and if left unnoticed created a puddle and made the fridge run overtime. I solved the problem by placing strong magnets inside the fold of the magnetic seal at the handle end of the door. This is the flap on the outside the door seal. I used six magnets on the top and six on the bottom. The magnets were from discarded Sonicare tooth brush heads. They are very flat and super strong. You can find something on ebay. My freezer door doesn't budge problem solved. I did call the company and told them I solved the problem and they still insisted it was the leveling. Good luck, Art Knapp

Some leaks actually are from the windshield and it is contained by the trim so you can't see where it is leaking from. If it is the door seal look at the striker bolt to see if there is any abnormal wear. Make sure the striker bolt is aligned with the door striker. If you don't know how to check this run by your local body shop and ask them to check it for you. Sometimes if the keys have ever been locked in the vehicle people use door shims to hold the door open as to pick the lock. This is bad because it knocks the door out of alignment with the seals. Hope this helps.

If all else fails...take pins out of hinges and remove door to get to lock bolt.

you'll need to remove your door panel (screws are by the door handle, arm rest, under door and side of door) and pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything.

I'm not sure what you mean by lock barrell.. I'm guessing the cylinder which you'll just have to bolt back onto the door.. you may need to find a specific bolt though....

the first thing that i would do would be to take the inside panel off and disconnect all of the wiring that comes into the door from the vehicle and then remove the bolts that are holding the door to the frame.

well the seatbelt in the front of a car are very strong and should be bolted in both from the underneath of the car in the middle and on the edge of inner door seal, most upto date cars there will be a cap which removes from angle at top most point of seat belt to undo. all bolts should be lock tighted(chemical metal) to seal and not undo in unlikey event of bad crash.
