Adding keyless entry for CRV?

[rkruz]

Other then going to a dealer to have installed (where dealer tried to sell it to me for $1000), can one have purchase a retrofit kit or have this retrofit done somewhere to add keyless lock for a 2003 CRV? I suspect if so it will be a lot less then dealer charges.

If so, can you provide some hints where to buy or have this sort of thing done?

thanks!
