Setting Up SQL Server Encryption Between Multiple Servers And Databases

Greetings.

I have a setup/deployment question regarding SQL Server Encryption.

Internal database encrypts data in 3 different tables. This could execute on any one of 6 different servers.
The tables with encrypted data are replicated to another database on different servers (3)

How should the keys/certificates be created so that the data in the replicated database can be decrypted?

In my test scenario so far, I have been unable to have the second database decrypt the data that was encrypted on the first database (currently on the same server).

-- Create Database Master Key
CREATE MASTER KEY ENCRYPTION BY
PASSWORD = 'p@ssw0rd'
GO

-- Create Certificate
CREATE CERTIFICATE MyCertificate
WITH SUBJECT = 'My Data Encryption Certificate',
EXPIRY_DATE = '10/31/2010';
GO

CREATE SYMMETRIC KEY MyKey
WITH
ALGORITHM = AES_256,
IDENTITY_VALUE = 'My Symmetric Key',
KEY_SOURCE = 'Unique phrase that will be used to secure the key'
ENCRYPTION BY CERTIFICATE MyCertificate;
GO
