451 flashing fuel bars ?

[martininkent]

hi i have a 2010 cdi and the immobilizer key does not appear in the dash, just the constant flashing of the fuel bars along the bottom of the dash, and no start, also no ecu communication too the car via MB star,this has had a additional immobiliser fitted at some time , i bought the ar from a repo company with the knowledge of this and some one has tried to removed it partially, so this is where iam at, any input appreciated

Mine has no key on the dash ever. I assume they are all like that. I have seen no evidence of them having an immobiliser.

There are pictures of a fully illuminated LCD on Evilution and FQ101 and IIRC there is no key symbol.

The 451 does have an immob

Unless I am reading the file incorrectly it is only an option from 07 to 14, standard before and after that.

I reckon very few people will have taken the option up, I certainly wouldn't, more trouble than they are worth.

Am I reading it wrong, certainly my alarm has never gone off or beeped or anything.

Sorry , Page 29

Smart Fortwo (07 onwards) AKA the 451 listed as having a Cat 2 ( which is just the immob)
Smart Fortwo (14 onwards) AKA the 453 listed as having a Cat 2 (which is just the immob)

Cat 1 is an alarm as well , and on most smarts that was an option , although they did put the alarm on as standard on some of the early 453's (particular models)

The earlier models (prior to 07) are listed there too, although they only seem to start at 03, maybe that's when the official 450 RHD came in this country?

Thatcham used to be a lot easier to search for a particular model when they had a search facility on their site, now we have to put up with a compiled PDF.

Right, found it now. Inability to read, as usual.

Immobiliser as standard, alarm optional.

There is no sign of it anywhere though, not that I have seen, nothing on dash or lights or owt.

hi
it came with no keys, i have many used keys, but whats my best route, read the chip with upa or xprog etc which i have , or buy new virgin from ebay, or buy a full lock key and ecu set, i have remove barrel so now i can switch the power on, but star etc will not read the meg / sam etc it says no connection with datlink , i dont think they are wakeing up,

can i do anything with the spare 451 keys ? some people are saying get avdi autocom , or skp900 or what ever
can the chip in a used key be read and edited then work ? whats best way to deal with this, thanks

It is worth putting significant effort into tracing previous owners for the right key. If that's a no then let me know what you did I only have one key for mine and could do with another.

I too have some blanks and spare innards but when new, the chip in the key needs programming if you get the Chinese ones and I have no idea how to do that.

I do have a full set of electronics for one but it is early 2009, different ECU map for the older glow plugs and Euro 4 spec not Euro 5.

This shows a key symbol on the dash at 45 seconds.

I have never seen it but I changed my LCD for the earlier one with the temperature gauge a while ago.
