Foreign nationals holding a Malaysia long term pass and a biometric passport have been able to use the Autogates at KLIA and KLIA2 for the past 2 years, and I have used them many times.
Initially, visitors from 10 countries were eligible:
Using the Autogates as an LTSVP holder
As an LTSVP holder, before using the Autogates I first had to be stamped out and back into Malaysia at the manual counter, and my fingerprints scanned. I could then use the Autogates the next time I travelled out of and back into Malaysia.
After I renewed my passport and transferred my LTSVP, I again had to be manually stamped out and back in to Malaysia before I could continue to use the Autogates.
Using the Autogates as a PR holder
After receiving my PR I checked my eligibility to use the Autogates on the Immigration website: https://imigresen-online.imi.gov.my/mdac/egate
It showed this message that I am not eligible to use the Autogates:
It would be a surprise if LTSVP holders and tourists can use the Autogates but PR holders cannot.
Hopefully I just need to be manually stamped out and back in to Malaysia, and that I will then be able to use the Autogates on subsequent trips.
