LS430 Not Locking

[Micholas]

I realise there’s a number of things that could be causing this, but my 2001 LS430 with smart lock is not locking on all four doors. This is the same with me pushing the button on any door or trying to use my smart key (I only have one). 
Things which could impact this. I had a flat Battery last week which I replaced. I also did a lot of work on the drivers door at the weekend. Removed actuator, window, replaced the whole window guide etc. Everything was plugged and bolted back together. Today I’ve double checked that nothing was missed and all was ok. 
 

Any control units known to be weak points? Anything else I could be missing? 
 

thanks

Hi

Which door is not being locked - the rear drivers side doors often has problem

As stated, all doors aren’t locking. So not a actuator issue on any particular door.
