keyless entry problem

Hey OH, got a small issue with my immobolizer/ keyless entry remote.

My car immobilized itself and wouldn't let me start up, i had to disconnect the car battery to get the car going as the buttons on the keyless entry remote didn't work . I thought it might be the batteries on the remote, but i just went and bought new batteries and the remote still isn't letting me unlock/lock the car, doesn't even try to. Have tried the spare remote too which also doesn't work.

Anyone have any suggestions on what might be up?

its a try, but have u checked your fuses? i mean for your immobiliser/alarm?

Maybe there is an interference by the nearby electric wave.
