- lost my suzuki motorcycle key

It's unlikely, despite all the 'reports' of people having keys cut from numbers or dealers looking up the original key cut, etc. Talk to any REAL locksmith, they'll tell you. In the end, if you have any other lock off the bike that you can TAKE into a good lock shop, they can make a key from that lock for likely under $50. Like, an accessory or helmet lock. Taking it to a smith will SAVE you $$$. If you have a smith COME to you, figure $100-300!!!

Sure, some folks have had it done for free, or only $5, or only $10, and the stories go on and on--if you're brother in law is a locksmith, take it to him, or whatever--a real locksmith is a professional who's got to make a living--they charge reasonable rates.

That said and done, I recently had to do something EXACTLY like this, but I'm too cheap to afford the $50 for a smith to do. I bought a blank key for my motorcycle type: $2.

I bought a needle file set from Harbor Freight, on-sale: $1.99

I removed one of my trunk locks (Goldwing, full dress), and figured out how the 5 tumbler lock works, and I filed a key down with tiny files to open this lock. It took 20 minutes, I was patient and methodical. When I went back to my bike to try the key, my new key was smoother than my OLD key. Since the trunk locks don't get as much use as the ignition, my 30 year old ingition lock was a bit sloppy, and the original key, a bit worn. A sharp, cut key from a tight trunk lock worked out NICELY for me.

Maybe I was lucky, maybe you can be too. It's all about what you want to afford, and how much effort you want to put into it. I had a lot more time than money when I did this--it paid off.

I would just hire a locksmith. I think that he would be able to help you get your bike on the road again. I have no idea whether you can get a new key made from the serial number. My guess though is that you cannot. Maybe you can visit the dealer where you bought the bike and see if they could help you.
