Hi,

 

I like the idea of being able to unlock and lock my Mini remotely with the Rover fob, I've had a look online and seen a few kits and read a few threads, but I'm still not sure how/if it's possible to use the Rover fob with it.

 

I've seen that A-Series Spares used to have a more mini focused kit, but they seem to be long gone.

 

Thanks for any info.

The 5AS unit has 'CDL Motor Lock' on pin 13 & 'CDL Motor Unlock' on pin 11 which drive the door locks on Rover 25/45/MGFs.  Tested this on the bench with a spare unit but have not tested with the in-situ 5AS, both present +ve active for ~1s on change. 

 

Additional pins can be added to the connector in the car - Andrew Revill has a posted a lot of research into the 5AS for his Caterham and has detailed the connector specs: andrewrevill.co.uk/5ASConnectors.htm.  Looking at the R45 wiring diagrams, the wire spec is "0.75D" which translates to 0.75mm²  single core DIN.

Ok wow I don't even know what the 5AS is, I was hoping there was a kit I could use which would be fairly simple to wire in.

You may want to check out John Brown's blog where he retrofits central locking to a LR Defender: DiscoverThat - Journal: Central locking PoC

 

Although his Defender uses the Lucas 10AS immobiliser I believe they are  in many ways similar in operation. He is using aftermarket lock actuators.

 

The question is whether the 5AS has the CDL outputs enabled on the Mini by default - I have not tested this (anyone know? ), if not then diagnostics/programmer would be required to enable it or replace the 5AS with a unit from a Rover/MGF.

I think the difficult part would be finding a central locking motor small enough to be used in a mini door. 

 

Any ideas what could be used ?

I've got the Central Locking Kit, Mini Spares used to supply, fitted on my '98 MPi.

It's been on the car for more than ten years/35,000miles.

Came with an "Interface Kit" that allowed it to be triggered by the standard immobiliser key fob.

It uses standard, five-wire door-lock motors that fit, no problem.

So you can still get the alarm interface, I just need to find where I can get the SPI/MPI specific central locking kit. I will email Mini spares and see what they say.

But it seems that they no longer stock the MSSK2004 kit which has the lock/unlock lever mechanisms.

Looking again at John Brown's Defender build he put the motor 2-wires between the 'CDL lock' & 'CDL unlock' outputs of the 10AS (which are pins 2 & 3 of his smaller green connector). Also wired the driver's door lock switch to 'Drivers sill - input' on pin7 of the 10AS larger grey connector.

For the Mini's 5AS unit, the equivalent pins are respectfully: 13 & 11 for the motors and 4 (SILL UP) on the large grey connector (later units also have a smaller white connector for the indicators to flash on lock/unlock). 

 

Checking on the bench, pins 11 & 13 are both are to -ve when inactive - putting a 5w bulb across these pins lights on lock/unlock (current reversal).  

 

For internal driver's CDL operation, referencing the Rover 45 manual:

Door latches - General

Each door has a sill button attached to the latch

mechanism. The sill buttons remain accessible in

the locked and unlocked conditions. The driver’s

door sill button when pressed, will lock all doors.

Pulling the driver’s door sill button upwards unlocks

all doors. Operation of any passenger door sill

button will lock or unlock the individual door only.

 

Needs more bench testing as I have been unable to get it to work as yet - pin 4 SILL UP, pin 19 SILL DOWN, both to -ve when active.

A quick update, I have tested pins 11 & 13 across a 2-wire lock motor (from a Peugeot 107) and can confirm the output is more than adequate to drive the motor - lock & unlock  Hopefully I will get a chance to check the sill switch lock/unlock function over the weekend.

Same system that I’ve been using for 5 years with no problems at all.  Would recommend it.

Those door lock motors are readily available online

[surfblue]

Just use the door key!
It's part of an old car's charm. I have central locking and keyless start etc on my modern car, more than happy to use an FS key on the mini.

Hi, Ive actually done a few videos on this that might help.

Good work and good luck with your resto of Timmy.

 

Thinking about keyless entry and start, my 1970 Clubman had both - just a screwdriver was all that was needed.
