Newer C-HR keyless fobs are not susceptible to relay theft method.
AFAIK 21 MY onwards have the upgraded keyless fobs.

I know of two other methods to defeat the security system but haven't really seen reports of any C-HR targeted in these ways.

Let's hope so but the above was a copy of the news item from Birmingham news, I always use a good quality steering lock (have always done for years).
Will having key in a Faraday pouch protect against relay theft?

It will if both keys are in faraday pouches.

IIRC the 21MY built C-HR onwards should be equipped with the newer secure type keyless fobs with motion detection that don't require faraday pouches.

Mines a 2020 Orange edition so guessing that's the less secure fob?

My chr new in June 2021 has lockable keys.....you press and hold the lock button (on the key) then (whilst holding the lock button you press the unlock button twice) the red light on the key flashes four times to confirm the key is locked ( does not transmit a signal until you press any button on the key again) try it ? However ymmv !

I see Toyota / Lexus have very recently released a 2nd immobiliser system for certain products in the line up.
Looking at the quick user guide it looks like a small key fob with a button battery inside, I would guess its either RFID or bluetooth.

RAV42018/11 FMC Gen 5, 2020/06 Plug-in Hybrid
Toyota C-HR2019/10 MMC Gen 1
NX2021/09 FMC Gen2
RX2022/10 FMC Gen 7

Part number is PW625-20000 - All I can see is the quick user guide, anyone wanting to upgrade there Toyota security might be worth asking your Toyota main dealer for more details.

I've found the OM for the system & it seems a decent thought out bit of kit.

Motion detection for the fob, plus if the fob battery goes flat the fob can be powered up via the vehicle USB socket so it can then disable the security system.

Also mentions it can be linked to My T for low fob battery warning & also to temporarily disable the system.
Every electrical system can be hacked these days.. i trust on my mechanical based Bear-Lock.
Does not consume any power and takes only few seconds to turn the gearbox on/off.

That few seconds does not get me free from a slammed window or any other damage. But my car will stille be parked where i left it.

You can also pull a fuse for the hybrid system every time.. or interrupt it. It won麓t start so can麓t move!

My 2020 orange edition also has this feature. Does this mean I don't need a Faraday pouch as long as I always lock the key fob?

Basically yes, if you lock the key fob it will stop the key transmitting a signal so a scanner will be unable to relay the signal to the car. You can check this by trying to open the car door with the key locked. Doesn't stop other ways for tea leafs to steal it though (obviously! ) and....you need to remember to lock the key.....
Just been speaking to my local dealer, the new Toyota enhanced security retrofit system isn't available yet but it's should be very soon.
There isn't any information on pricing yet either.

We are going thru a phase of
thefts around us they are hitting rural these are armed with low loaders caught some few weeks back.
They hitched the car up and hauled it on the back dragged it on gravel drive Nissan X trail, they took a almost new Kia Sportage about 6weeks old same trick found that in Harlow. The two they caught are part of a bigger picture the plod say. Thought the days of TWOC was gone,but apparently not.
Motorcycles have been targeted for years around me same as farmers quads etc.
Toyota / Lexus are well aware of it, newer models using the newer CAN architecture are immune to this theft method due to both a hardware & software change.

I know Lexus have engineered & have been testing protection plates for certain older models to stop access to the connector plug.
I've no idea if Toyota are doing the same.

The new Toyota / Lexus enhanced retrofit security system is also awaiting final approval before it can be offered as an accessory fitment option.

It won't stop thieves getting in to the vehicle with CAN invader but it will stop them driving it away.

Update on the new Toyota Enhanced retrofit Security System - don't bother with it as it will be easy to defeat once word gets around.
