You can drill thru the inside door and most of the way thru the outside door (top and bottom). Install a couple of 1/4" pins.
Had to replace the back patio door (kitchen/dining room into the yard) with a "slider" and less lockability than we had previously (French door outer-opener with full locks). It's a money thing and insurance will probably not pay for the replacement, so we're out two grand.
Ideas on how to secure it better than just a dowel in the left-side track?

They actually make a pin kit.
Go to your local home improvement center. Excellent auxillary locking devices for sliders are available and inexpensive.

Securing a sliding door could be a problem. I do not have one so I have never had to do what you are doing.
I agree with one of the posts that mentioned going to a home depot or lowes and getting suggestions there.
Have you thought about some advice from your local locksmith?

Something else too think about. There are many types of film that can
be added too windows/glass doors that make them harder to break and
enter.
It is expensive but if they really want in they will just bust the glass.
We have two full 8 foot patio doors that were replaced when we did
replacement windows and doors.
Treated patio doors were almost $3000 each.
The doors have the center lock plus locking pins at the top and bottom
built into the doors.
I have no idea what just adding a film would cost but a good window company could tell you.
It still won't stop them but it sure will slow them down plus make a lot of
noise getting in.
Before I retired I saw the tests on window film and other stuff that was added
too the mainframe computer room and floor when they got ready
for possible Y2K problems.
