You are asking for the Security code right? Not the Lock Code? Those 2 are extremely different. Well, the default Lock Code is 12345 on the 6555.
As for Security Code, if you bought your phone on a Network Service (AT&T, Verizon, T-Mobile, etc.) then you WILL not have the Security Code. This is for a very important security reason. The Security Code will let you have access on changing sensitive and critical settings on your phone. So, for your safety, the Network Service won't be providing you with the Security Code unless you unlock it to all networks.
If you bought the phone from a retailer, in your case, a Nokia Store, then the default Security Code is 00000 lest you changed it.
>The Lock Code is the code you will enter when you Lock your phone using Power Button -> Lock Phone.
> The Security Code is the code that is asked to you when you want to change passwords, system settings, etc.
