2012 Toyota yaris base model able to have keyless entry?

[Maddiesyardstick]

Hello everyone! I have a 2012 hatchback 4 door yaris that is the base model, no electric windows but it does have electric locks. I have asked the dealership where it was purchased if they had the key fobs for it and they said they do not sell any for the 2012 yaris' not even the more expensive models but they never told me if I was able to get an after market one and if it will work. I've had it since it was brand new and now that I have a small child I would like to be able to unlock it with the push of a button instead of having to put the key in the door while holding my son and other things. Will my yaris allow for an aftermarket key fob to be used? Also, is there a way to set it up where it will open the hatch as well?

Thank you in advance for your help!!
