When I bought my Rs250 I got only one key with the bike, it didn't help much that the glove compartment lock had been changed so now I had to have 2 different keys to operate the bike.
I talked to AF1 Racing and they could not ship a complete set for use with one key ,they could ship me the ignition lock,gas tank lock and glove compartment lock but then I had to use 3 different keys to operate my bike, this would be even worse.
Sure after a few weeks my ignition lock key slider got stuck so I bought a new unit to replace it.
I had a friend that worked at a caravan store and I noticed that many of the locks was made by Zadi, the same producer as the locks on the rs,I found a caravan store in the Uk that I bought 3 cylinders from and hoped the internals would be the same and that I could reprogram the gas tank lock and the glove compartment lock to use the same key as the ignition lock and it worked perfect.

This is how to do it.
These are the locks from the caravan store, as you can see the barrels are different - I will be using the Rs250 barrels but with new parts from these.
Aprilia glove compartment lock on the left, caravan lock on the right.
This is how I removed the crome cover on all the locks, be careful not to overbend the steel tabs on the crome covers.
Crome cover removed, internals are the same.
Pull the rod out to release the pins and remove the springs.
Here are some of the new parts I will be using, new springs, new rods, new plastic sliders, pins and new crome covers.
Here you can see the three different spring types. 6 springs for the 6 pins, 2 springs for the plastic slider and one spring for the lock plate on the right. The lockplate on the right is the plate that is not in use with the regular key, this simply holds the lock in place and does not move when normal key is inserted - when you remove the glove compartment lock this is the plate you press down from the backside of the compartment door the be able to press the lock out - same thing goes for the gas tank lock.
Clean the rs250 cylinders well and if you have to use some of the old pins clean these too.
As you can see wrong plates have been fitted to match the key, the 3 plates closest to the key poke out on top and below meaning you can not twist the lock around and open compartment door.
Same here with the gas tank lock, plates sticking out is wrong.
These are correct fitted, none of the plates is poking outside of the cylinder itself.
Fit a new plastic lock slide with new springs and new crome cover.
Success
Caravan cylinder on the left and gas tank lock on the right. Internal parts are the same for compartment lock, gas tank lock and caravan lock even though the cylinders are different.
Old gas tank lock with worn crome cover.
Fitting the lock, clean the surroundings and fit the rubber seal.
Place the lock plate that never moves on the angeld piece and press down and rotate lock.
The lock plate should fit in the deepest grove and will automatic pop out and hold the lock secure.
And success again, locks programmed to fit the ignition key with new internals and crome cover.
Hopefully this will help some of you, before I found this solution I bought a complete set of locks and keys on ebay - sadly they were worn so much I choose not to fit them and choose this solution instead.
