Replacement key with remote locking transmitter

Matbat: That system is interesting. If you have time to post some pictures, I would be interested in seeing how you integrated the push button start and keypad.

Thank you all very much for all of your support and information.

Unfortunately (or perhaps fortunately), I had already bought a second hand (but almost unused) original Suzuki key with integrated remote transmitter before I read what Delux wrote.

The key is still on it's way to me.

However, two Suzuki dealers in my region told me that they can reprogram a used (already programmed) transmitter and immobiliser in a key, and that I will only need to sort out the issue of getting and cutting a new blade at any capable locksmith.

Both of those Suzuki dealers are a bit far away (200 km in one direction) and I have to visit them during working days because they have to do the reprogramming while the master Suzuki factory in Hungary is open (direct data link to the master factory is required during reprogramming and the vehicle has to be present at the dealer).

Since I got this key for about 20 EUR, and the programming will cost me about 40 EUR, I might be on a win here. Compare that to the quote of almost 200 EUR for a brand new key + programming from the dealers.

Anyway, I will report what happened - whether Delux's statements about not being able to re-program a used key is true, or if they really can do it. I just have to get a free day from work and make it a single-day holiday trip of 400 km in total and find some cheap petrol ...
