this new motorised roller shutter doesn't seem to have a lock...is that OK ?

Are you talking garage door? If so, nor does mine. It relies on it not
being possible to raise it other than by coiling it back up onto its
axle, either electrically using the remote controller or with the hand
crank inside the garage if the electrics should fail. I asked about
security before I had it installed, and the guy said it was very
secure (BHWSTWH).
Out of curiosity - what happens if you're not in the garage, the power
fails with the door closed, and you have no other entrance into the
garage?

At least some (if not all) have a winding mechanism accessible from
outside if there is no seconary door.

http://www.bradfordgaragedoors.co.uk...power-cut.aspx

External winding handle access point (low level)

Used in insulated roller garage doors when there is no other door
allowing access to the garage. This involves feeding the internal manual
override system to the outside of the garage through its brick wall. A
steel plate is fitted over an access point and this plate is lockable.
When unlocked, the winding handle can be fed in through the access point
and be used to wind the door up or down until the power comes back on.

External winding handle access point (high Level)

For roller garage doors that are fitted externally, with the manual
override being accessed from the outside. This type of mechanism also
has an access point covered by a lockable steel plate which can be
unlocked to gain access to the inside and wind up or wind down the curtain.



Not really any different to any (garage) door where the lock fails, save
you just have to wait for the power cut to end rather than get more
creative. Having helped several neighbours over the years with garage door
issues, waiting for a power cut to end could be the better option.

We have a secondary door so it isnt an issue but it was something I
thought of. The roller doors are quite hard to wind up by hand, at least
the double ones. Trying to (somehow) push one up so it winds must be all
but impossible. You could smash it open but that is true of any almost
door.
