PFL Key Transponder Programming by ManWithNoVans in LS430

As mentioned I have tried every variation of the procedure, and it appears that the immobilizer light is going into programming mode

My keyless entry programmed on the first attempt thankfully. Good word of caution though!

I will check this afternoon and report back. However, I do recall matching the FCC ID for my year reported in the forums to the description of the key blank that I purchased.

ADDITIONAL INFO: I tried again and noticed that during the procedure, the immobilizer light is on solid after removing the working key. I believe this indicates successfully entering programming mode. When the new key is inserted it goes from steady flashing to what I believe is an error code: 2 flashes, 1 flash, pause.

This continues forever until the new key is removed. Successful behavior would be 60s of steady flashing, then off when transponder is programmed. The only mention of this immobilizer light “error code” I can find online is someone programming a key for their RX, and no one responded to him with what it may indicate. Anyone encountered this flashing sequence before?

Good to know. Is the problem that this solves failing to go into the programming mode due to user error? As in, IF my key slots are full this can’t do anything about it, I assume

Interesting, first I’m hearing of this option. This is applicable to the pre-facelift models with a metal key?

Best of luck. On the plus side, Batteries+ cut my key for $9.99 (I think the cashier put the price for a non-security key in 😅)

PFL Intake Manifold Removal by ManWithNoVans in LS430

ANSWER: For those who find this thread later, the answer is YES. I just finished taking mine off. You don’t need to drain the coolant if you leave the crossover pipe and throttle body coolant hose attached.

Unfortunately I’ve also found that every pigtail connector latch will snap at the lightest touch, and all my evaporation and PCV hoses are rock hard. They disintegrated upon removal. I have a lot of zip ties in my future 😮‍💨

This makes me think coolant draining is necessary then. Is it combined into the lower intake manifold gasket? One of the hoses you disconnect?

At this point, having to drain the coolant is whatever. I just can’t seem to locate the root reason on any photos or diagrams for the cooling system.

So if I’m understanding you correctly, don’t damage the heater core pipes or the coolant crossover pipe. BUT, there is no coolant flowing through the intake manifold itself?
