Does my 2007 Civic Coupe EX have a immobilizer on the ignition switch? Has the factory alarm. Got the car with only one FOB key. Had a valet key made for $100 at the dealer but it seemed to do everything. Now grandson has broken the FOB key at the base where it joins the plastic. Still works. Took it apart and at first appeared I could swap it out with my extra 2005 CRV key body but they are different. The CRV key has a little 1/4x 1/8 immoblizer on the side of the case. The 2007 Civic does not have this. Not sure where it is unless it's in the FOB case with the battery.

The Key Transmitter top case and blank is only $22.75 35113-SVA-306 and the lower is $3.51 35116-SDA-A11

Sure looks like I could get these two parts and have the dealer make me a key from my old one without taking the car to him to have it married to car for $150. He just quoted me before $100 valet and $150 of FOB key when he made the valet. Any thoughts? Civic is 2HGFG12847H530848

The 2005 CRV top case 35113 S9A 305 is $69. go figure?? same bottom case as Civic

You definitely have an immobilizer.

If you take it apart as to change battery, can you see a black rectangle on the PCB. I can on my 2010. But that may be different on 07.

One of my keys was eating batteries so when getting a new module the mechanic said he had to program both the fob & the key (I think my immobilizer is on the PCB) He has HDS.

On my 05 CRV, the immobilizer is on the key case 1/2 with the key since it will start key with the FOB part with the buttons and battery taken out. Have not tried that with Civic since Grand son is at school (worked on car yesterday when I noticed key)

Are you saying you think the immobilizer on your 2010 is in the alarm button part with battery Not sure what you mean by (PCB ???) (HDS ???)
If your Car is a 2010 Civic, it calls for the same key case , blank and transmitter as my 2007 at parts fish at College Auto...

I believe immobilizer RFID chip is on the board (printed circuit board)
Maybe not.

HDS is the electronic tool that the techs use for adjustments, and diagnostics.

I will check the manual for more info.

Sorry but if you change the key "shell" you will have to get the new one programmed as well. I would strongly suggest getting extra plain keys made as well. The plain key that does not include the key fob is usually only around $20-30. You can have a maximum of 6 keys total so you could have 2 fob keys and 4 plain keys. If in the future you ever did break another fob key you could just hang it off of your keychain like it was just a fob. If you get extra keys made you only have to pay the programming once. It doesn't cost more to program 3 keys compared to programming just 1.

Oops, sorry had it backwards. The shell doesn't contain the immobi ID the keyless transmitter does. So they shouldn't have to program, but I still suggest getting extra plain keys cut anytime you pay for programming

Did a little checking but still do not have Civic..The first attachment is the 05 CRV with the immobilizer on the key body. Just that part will start key all apart.
Second picture is how the 07 Civic with no part like that on key body looks. No pocket or extra wall.

Starting with 06 Civic the RFID chip is inside the transmitter on the circuit board.
So..
You can buy a blank shell with the key shaft and get that cut to fit your car.
Transfer your original transmitter into the new shell.
The transmitter contains the RFID chip and is already programmed to the car.
It will work this way.


Test it out(?):

Break off the metal key shaft and stick it in the ignition.
Try to start. It won't.
Turn off.
Hold the transmitter up with the key shaft and try to start.

It should start if you get the transmitter positioned correctly so the RFID chip is close enough to the receiver ring.

01-05 Civic and 02-06 CRV (among some other cars) uses immobilizer type 3
06-11 Civic (among some other cars) uses immobilizer type 6

Thanks ezone, Now I just need to find out if I can see if service will cut it for me. Last time I talked to them, I had gone to parts to get the valet key made and they told me only service handled keys and my service man said $100 or $150 with alarm but that was to mate it too.

The metal key shaft broke out one corner and will actually turn and drop out, so I will double check it. Are they going to have trouble holding it to duplicate it?

While I have your attention, I replaced drive belt at 108K since it's hard to inspect. It actually looked perfect..totally amazing. However, I noticed this bracket with two holes and two tapped holes in block. It does not appear parallel to block but it is. The holes are just offset from the bracket. Is that to support engine with some type of spacer to remove motor mounts?

In my store the parts dept sells and cuts the keys, and service does the programming.
If you bring in the car to be programmed it's all on one work order and you just flip out your credit card at the end.

=======

Stroll in and ask 'if you order a key through them does the price include cutting it to fit the car?' (You know, like a wallet key-- no programming needed, only works the door.... can't start the car. LOL)

then order the part number of the blank with empty shell.
Cut the blank, no programming.


If they will cut any key blank for a cheap enough price..... go internet ebay/amazon and get a cheaper one. with the right number of holes for the transmitter.

Local locksmith shop???
Our machine clamps lengthwise.
Or they can cut by VIN instead.

Take proof of ownership, prove you aren't a terrorist.



The bracket is just there, it's not used by us (me) for anything (I really have no idea why it's there unless for something equipped elsewhere in the world)......

and you ought to fix that oil leak, it looks ugly.
Front crank seal, or tensioner cover?

Post this for a thread back that adds to this. Not sure why I could not find this the other day.

Appreciate all the help ezone, I did not pay much attention to that mess. It was pretty dry baked on. It's not wet under car or any drips and the crank is not leaking since I looked up under there. Probably from sloppy maintenance.

OP when they made you a valet key recently you had mentioned....is it a true valet, that wont open trunk, or floor opener cylinder ??
If it is not they could use it to copy from.

I got a flat metal key from the dealer (wont start the car) for $10 $5 for key & $5 to cut it)

RIPSAW

All fixed up. $48. Did not need car..just proof of ownership. They cut it from the VIN number. The valet was cut as a full key as I recall. However, if not, the only thing it would not work is the lever on the drivers left floor. Interestingly, an 07 Civic Coupe EX has no glove box, trunk or passenger door key hole. I did not ask them if they would cut my blank. You can get one on Ebay for $2.00 up no less. Going to guess it's junk and that they wanted $50 to cut it to make myself fill better.

I think the picture I posted above in 9 on the bracket is to bolt the special Little Girl Japan crank locking tool and lock the engine to prevent motor mount damage for removing and torquing the damper pulley bolt.
