Pakistani nationals can transit in Malaysia without a visa provided:
- TWOV cannot be offered to passenger sponsored by airlines other than
Malaysia Airlines and Air Asia. At present only MAS and Air Asia have
agreed and accepted all terms and conditions imposed by the Malaysian
Government.
- TWOV facility is not available at entry point other than Kuala Lumpur
International Airport (KLIA) and Low Cost Carrier Terminal (LCCT)
which means your friend will not be allowed to change airports in Kuala Lumpur. It is only possible to transit without a visa if your friend travels on Malaysia Airlines or Air Asia.

Can't a transit visa be issued at the airport to go to that terminal
if the person is willing to pay?
No, no visa will be issued at the airport for Pakistani Nationals if they are planning to change the terminals. However, there is a exception if your friend has a valid visas from:
Source:Ministry Of Foreign Affairs Malaysia
- Australia, New Zealand, United States of America, Japan, China, Taiwan and South Korea.
- a max. time of 120 hours, arriving at and departing from Kuala Lumpur (KUL) on Malaysia Airlines (MH) or Air Asia (AK). When transit time is longer than 8 hours it is permitted to leave the transit area
If your friend meets the above requirement, then he will be able to change airports; otherwise, I am afraid he will have to change tickets.
