Keys has wound up Hammers fans this season, by consistently referring back to Sam Allardyce’s time in charge at Upton Park.
The 58-year-old pundit is a major advocate at Allardyce’s managerial style, and has appeared to suggest that West Ham were wrong to sack him.
However, Keys has now asked for West Ham fans to call a truce, as he believes Bilic has proven to be a good appointment.
"Regarding West Ham. Yes, I warned supporters about being 'careful what you wish for' when Big Sam left the club. I stand by that statement, but so far so good for Slaven Bilic," he said.
"I like him. He's doing a terrific job, although the Hammers are once again a point behind their haul at this same stage last season! I only started the in-going comparisons with West Ham fans because of the hysteria over their start. Let's call a truce and visit this subject again at the end of the season."
Allardyce always was a divisive figure at West Ham, and he never managed to win over all the supporters at Upton Park.
Bilic, however, has the full support on the Hammers’ crowd - after making a hugely impressive start to lift at the London club.
West Ham have picked up some notable scalps over the season to date, and they are currently in sixth spot in the Premier League table - leading to talk of them claiming a European place.
