Craig Bannisterâ€™s 25th goal of the season was enough to earn Khalsa their eight league win on the bounce and avenge their loss to Lye, the last time they tasted defeat.
Bannisterâ€™s goal on 48 minutes â€“ a fine effort from range threaded into the far corner â€“ was decisive, but two fine saves by debutant keeper Charlie Price proved equally important come the final whistle.
Bannister might have bagged a couple in the very early exchanges, two half chances ending up not worrying keeper James Bedford.
Lye fired a warning shot on 41 minutes when Dreniz Bala surged clear of the defence and lobbed a shot well over Priceâ€™s crossbar.
Then, on the verge of half time, Price made the first of his vital saves, a Lye corner finding captain and top scorer James Spray whose brilliantly acrobatic overhead kick was destined for the net before Price produced a brilliant save to tip over the bar.
When Bannister scored what would be the winning goal just three minutes after the break, that save was to appear even more important.
For a good while afterwards, both sides laboured in heavy conditions but the dynamics of the match were altered on the hour when Bala somehow talked his way into a straight red card after a volley of abuse at the ref.
This was always likely to have the effect of perking up a side of Lyeâ€™s quality and so it proved, Kieron Northwood forced a save from Price on 66 minutes as Lye stepped up their tempo.
Nisbett had a decent chance at the other end after a good penetrating cross from Martin and Mike Perksâ€™ effort after a lay off by substitute Nicky Campbell flashed just wide.
With ten minutes to go, Price pulled off the second of the match-winning saves, pushing Sprayâ€™s curling goalbound effort wide of the post.
The final stages saw Lye continue to push for the equaliser with nothing to lose, the most dangerous attack being a decent effort by Kalum Evitts forcing a relatively routine save from Price.
With moments left, a careless tackle from Martin gave Lye a freekick well within range but Sprayâ€™s first and second attempts were charged down by Campbell.
