It sounds like you are treating all keywords as reserved words and so not allowing them to be identifiers. You will need to change your rules.
Instead of referencing say ID directly use a parser rule id and add the keywords that can be ID in to the rule:
id : ID | KEY1 | KEY2 ....
You can change the token type of the keywords in that rule. You may need to add predicates to avoid ambiguity warnings.
