Can I buy a new ID40 chip on its own and get it programmed... and glue the key back together if necessary? I have all the pieces,  sans chip, that a good dose of glue will hold together...

The car needs to be programmed to accept a new chip.  do you have the Security Card Code for the car?

I would be outside now with a bright light picking over the gravel to find the missing chip

No offence to the OP, but knowing whats involved and without a spare key, I wouldn't have given up looking for it yesterday.

If you'd seen the hail storm, you would have!

Plan A is to find the chip. Can't have gone far.

Plan B is a new chip in old key. Theres a possibility that one of my colleagues has an imitation Tech 2 or code reader which can do keys... in which case I just need a car pass from the dealer.

Plan C, we will use if necessary!

Tell me more. .. I freely admit im a beginner with the electronic side of things...

Voldemort has a poor track record when it comes to ecu coding.

If you have the car pass, then it should be a quick run to Mark and job done. If you don't have the car pass, get one

Finding the chip is the simplest solution, then buy a key blank, get it cut to match original and fit the original chip/fob to it. Job jobbed

Awful feeling it's been washed away in one of the storms I ran inside and hid from. Not helped by being on a gravel driveway...

...I shall go and check out the FAQs for info but what am I looking at for a new usable key? A kidney?

In March 2014 my son Ben complained his 2.2 would not start. I  changed the crank sensor (nasty job) to no avail. He then confessed he had dropped his key in the drive and it had fallen apart. He popped the fob back on again, seemed OK, but car would not start; then I thpught he might have lost the transponder. I asked him where he had dropped the key, he said on the drive. This had been 2 weeks previously. The drive is tarmacadam. I spent half an hour on my hands and knees looking for the transponder. Amazingly I found it. I put it back in the key fob and all was well. I know I was lucky, finding it, and not crushed by other cars.
It's worth a good search! Pic follows.

Have dug up half the gravel around the car and sifted it by hand! No joy... 

[Andy B]

Ages back I had an Astra that had two keys, but only used the one. One time I was sat on the floor while working on a car and found chip ...... didn't know I'd lost one  ..... it was from the 'spare' key!

On the odd occasion when my key has come apart, it's usually been when I have been (whilst in a rush probably) turning the key to take it out of the ignition. On each occasion, I found the chip on the drivers rubber mat; difficult to spot as it looks like a piece of gravel that collects from your shoes. Unless, of course I've missed something and you were outside the car at the time....

I've mentioned this before; If your key is loose enough to come apart, then you should glue the chip in place! It doesn't need much, a dab of superglue or even from a hot snot gun will plenty. And then you won't have to grovel about on your hands an knees looking for the thing.
