How do get my key to start my car again?

I should start by saying it is a manual, ford focus mk1
Y reg. Its the 1.8l petrol 3 door version.

So, i took my heater controls off my dash to replace my blower switch as it was faulty ( like in most ford focus's) and when i was done i thought id reprogramme my key ro try and fix a locking issue i have with my key fob. So i put the main key (one with the remote fob) in the ignition and turned back and forward to from position 1 to 2 4 times to enter the programming mode. It beeped once, i then pressesd the locking button. It beeped again. I then removed the key and tested the locking. It didnt work. Oh well i figured.

Later. Upon going back to my car, neither key will start it. The electronics come on, and the immobilizer light turns off after being on for 3 or 4 seconds, then when i turn the key to ignition, all i get is the starter motor ticking, no engine turning at all. I have tried disconnecting the battery for 5 minutes and still the same. I have also tried the key programming again, to no avail.

I would have thought id accidentally unprogrammed the keys, but you should need 2 keys to unprogramme any, and the immobiliser light switches off, with surley indicates that it recognised the key?! So im completely stuck. Any ideas?
