Keyless entry / Power lock question.

[aquacryptid]

I have power locks and I want keyless entry. I bought my '99 used and I was wondering if it might have come with keyless entry. How can I tell?
Also wondering what is typically required to install the keyless feature? ie: price, components, modifications

Sorry if this has been answered before. I could not find the answer using search.
Thanks

Its not hard to put in, just take your time. I bought my kit for about $30-40. I have a 99 also with power locks and not keyless entry so i doubt you have it. But its not a hard job at all... just kinda slow..

I don't even know what to look for. What brand did you get?
Is anybody out there aware of the options for my scenario? (ie: powerlocks, not keyless)......................still researching..................TIA
