2006 S-Type R

I noticed that I can lock my doors using my fob, but if I come back to the car after 10 mins or longer the key fob no longer works, I have to use my key to unlock the door. And then once it's unlocked and I open the door, my car alarm goes off! I can then immediately get it to turn off by pushing the unlock or lock button on my key fob. Once I get the alarmed turned off my key fob starts working again. But when I leave again I have to go through the working-not working-unlock with key-alarm blaring cycle all over again.

A key shop told me I need a complete new fob and program for it at the tune of $220. I started troubleshooting and found that my left passenger door's lock actuator wasn't working. Could this be causing the issues I'm having? I tried manually locking that door and re-locking and unlocking with the key fob but it doesn't seem to make any difference with the working-not working-unlock with key-alarm blaring cycle.

 

Welcome to the forums mikesbaron,

I've moved your question from General Tech Help to S-Type forum. This is the place to post technical questions about your model.

Anyone......is it my non working rear door lock actuator or a key fob issue?

 

All locks/actuators need to 'agree'. (be in the same state)

When one lock is different, an error occurs and the security system is NOT HAPPY.

Get the fault lock/actuator fixed and the rest of the system will likely work fine.

The driver's door module could also be faulty or have a LOW VOLTAGE problem?

 

Thanks for this confirmation. Do you have a recommended supplier or source for me to get the door actuator?

 

A salvage yard would be the most cost effective.

I sold my S-Type and only have X308 sedans And X100 4.0 SuperCharged Conv.s

I do have three X308 parts cars so I have my own salvage yard.

 

My S-Type R only has 87k miles and this actuator has already gone out. I'd rather have a new actuator rather than trying my luck with another used one that might have even more use than my current broken one.

 

Hi, I am having this exact issue. Did you solve the problem?

 

I didn't fix it, but only because I sold the car but it was the rear door actuator itself. It's an expensive and time consuming fix; so complex in fact that the normal car guy I use for stereo installs didn't want to touch it.

 

Hi. Can I as how you knew which door was the issue door.
I had to change something similar on my old land rover and know it's a painstaking issue but short of pulling the fuse out the horn I dont think I can live with this..

Thanks in advance

 

I could tell becasue the offending door was not locking when I tried to use my key fob.
