Door Lock Release Spring, MX5 Mk1

SKU: SI4177

Door Lock Release Spring

Quite often these break on the Mk1 rendering the door handle inoperable, and as they were never available from Mazda, the only option was to replace the complete lock assembly. Well, not anymore! We have had these little springs manufactured here in the UK to exactly the same specification as the original, right down to the tension and the 90 degree offset on the hooks. Fitting is simple, although removal of the lock mechanism is required.

Fits all Mazda MX5 Mk1 models, 1989>1998

Simple job after the trim removed. I threaded a length of thin cord through the spring before I started and formed a loop. Tied this to a convenient part of the door in case I dropped the spring. Used a pair of forceps to fit it.

Brilliant service as ever, bit tricky but once you find the correct position it went on (with the aid from my wife, as my fat podgey fingers were not up to the final task).i did buy 2, to have a back up, good job as i lost the 1st one in the bowels of the door...Good pic here...

Piece of urine. Two minutes to get the door card off, one minute to get the spring on. Sweet. Much better than the quoted £92 for the lock assembly plus an hours labour at £55 at my local grease monkey. (I should add that a pair of locking medical forceps were perfect for this job!).

Great product, worked a treat! and delivered very quickly as always.I'd been shamefully climbing over the seats of my R Ltd for over a month as I'd been putting off sorting out my stuck shut drivers door - stupid as it was a piece of cake and took about an hour including finding tools (only needed needle nose plyers, a largish stubby philips and a thin small flat screwdriver in the end), and looking up some very helpful pics on the mx5oc forum ( got the door card off no problem, the popper things came apart fairly easily carefully using my fingers. It took me a while to get the door open, eventually I worked out which lever to pull. I think I'd pulled the right lever early on but had accidently locked it without realising so it didn't work (doh!), it took me a while to figure out what I'd done but I got there in the end!Anyway I managed to get the new spring in ok, I did the outer end first, used the small screw driver to hook the other end near the hole it goes in (pretty easy to see this when you're looking at it), it stayed in place near the hole long enough to get my hand in and guide it home. BINGO! a working door.I sprayed some spray grease on anything that moves to try an protect and lubricate everything, and it went back together a treat, even all the poppers popped back in!£6 inc postage for a simple little spring is a tiny bit steep, but a fixed door for £6 is a total bargain so 5 stars from me - wish I'd done it a month ago lol.

With a decent light and long fingers I find I can replace these by gradually working my hand through the rear aperture in the door frame, but I accept no responsibility if you get trapped by your Mazda in the attempt!. A long pair of narrow tippled pliers and steady hands is probably a smarter idea, but either way it can de done without removing any of the mechanicals. Certainly the first thing to suspect if one of your doors won't unlock.

After months of having the door trapping me in and garages telling me the central locking was shot, I purchased this from mx5 parts after a chance remark while ordering something else. They were spot on. I found the old spring in the bottom of the door. 35min job to fit. You don't have to remove the door mechanism to fit it. After disconnecting the rods from the internal handle and central locking mechanism there was enough room to get my hand in and with a bit of fiddling fit the spring. Job sorted. Just look at the picture of the full mechanism to see where it fits. Thanks MX5parts

Simple fix for jammed door handles. There is no need to remove the lock, you can reach in and attach the new spring with your fingers. Just need to take door card off and pull back inner plastic (what is that horrid black sticky stuff?!!)Excellent fast delivery from mx5parts as usual!

Delivery Information - MX5 Parts

We understand that its really important for you to receive your goods in a timely fashion and for a competitive price. To ensure that we can deliver this we have developed a strategic partnership with both the Royal Mail and our courier partner, Think Worldwide.

At the present time, we only offer one delivery option ‘our carrier’. We will dispatch your goods with the most suitable carrier, for main land UK deliveries this is normally Royal Mail 1st class for packages weighing under 2kg and Think Worldwide for those that are over.

Our delivery charges are based on the weight of the consignment and the destination address. For UK mainland deliveries they start at £2.95 for a package weighing under 200g and rise to a MAXIMUM of £9.95 for a package weighing 2kg or over (EXCEPT very large bulky items that have an additional shipping surcharge added). The exact delivery cost will be clearly displayed at checkout.

Delivery times are estimated at 1-3 working days by Royal Mail, and 1-2 working days by Think Worldwide for mainland UK addresses. If you order before 3pm, Monday to Friday, we will dispatch the same day. If you order after 3pm, we will try to dispatch the same day, but if we cant it will be the next working day. Items ordered after 3pm Friday or over a weekend will be dispatched Monday. Items dispatched on Friday are for delivery the following week. Items ordered over a Bank Holiday will be dispatched the next working day. MX5parts is constantly updated to keep pace with changes in our stock but demand is high and we occasionally run out of popular items. If we have run out of stock and can’t dispatch your order the next working day, we’ll email or phone you with a revised dispatch date. You can then either accept the revised dispatch date or cancel the order, as you wish. Please note, shipping times are an estimate, and can not be guaranteed. Please note that during special offer periods, dispatch of your order may be delayed slightly due to high a volume of orders.

A signature is required for ALL orders delivered by Think Worldwide. Someone must be at your delivery address to sign for your parcel between 8am and 6pm on a working day. Please send it somewhere it can be reliably signed for, like your place of work, a neighbour, or perhaps your grans. We can (but we don’t like to) ask the courier to leave your parcel without a signature. If we do this, it will be YOUR responsibility if the parcel is lost or damaged. If you want it left, you need to give us your express instructions in the ‘additional information’ box at the end of the checkout process. It would be helpful if you could also indicate exactly where the package should be left.

If you need to change your delivery address, for any packages that have been dispatched with Think Worldwide, there will be an additional charge of £9.95 if the package has already been dispatched.

Please remember, even with Royal Mail deliveries, that any items which are too large to fit through your letter box will need someone to be available to receive the delivery. If the item cannot be delivered, you will be carded and given the option of either a re-delivery or you can collect your parcel from your local post office depot.

Orders sent to countries outside the UK will be sent VAT free, however please note that on all international shipments, the recipient is responsible for any local VAT, import duty and other clearance fees that may be charged.

Our Guarantee - MX5 Parts

We guarantee that you’ll be satisfied with mx5parts!

You have our absolute commitment as fellow MX-5 owners, car nuts, internet users and hard-working people that you’ll be satisfied with mx5parts. If you’re not, let us know and we’ll sort it out!

We guarantee “always fair prices”

MX5parts maintains an everyday savings pricing policy. We watch other retailers closely and maintain competitive pricing. The internet being the beast it is means that any Tom, Dick or Henrietta can set up a website in their back room and charge bargain basement/off the back of a lorry (guv) prices. Often they will have no stock, no returns policy, questionable security, no guarantees and of course poor customer service. MX5parts strives to be open and honest, so we will never inflate our prices to set up an artificial ‘sale’ (a common – and illegal – retail practice).

It is inevitable in an open market like the internet that there will be some individuals selling some items cheaper than we do, and some selling them for more than we do, just as in the high street. We take great pride in offering a fast, efficient, friendly and secure shopping experience, with great products at fair prices. We encourage our customers to shop around, but are very pleased to welcome them back again and again.

We guarantee to despatch your order when we say we will

If you order before 3pm, Monday to Friday and we have your items in stock , we’ll despatch the same day . If you order after 3pm, we’ll still try to despatch that day but, if we can’t, we’ll despatch the following day. Items ordered after 3pm Friday or over a weekend will be despatched Monday. Items despatched on Friday are for delivery the following week. Items ordered over a Bank Holiday will be despatched the next working day. MX5parts is constantly updated to keep pace with changes in our stock but demand is high and we occasionally run out of popular items. If we have run out of stock and can’t despatch your order the next working day, we’ll email or phone you with a revised despatch date. You can then either accept the revised dispatch date or cancel the order, as you wish. Please note that during special offer periods, dispatch of your order may be delayed slightly due to high a volume of orders.

We guarantee to replace any goods which aren’t suitable

We guarantee to accept back any goods that you do not want, are not suitable, have changed your mind about, infact, for ANY reason, provided the goods reach us within 30 days of dispatch from us, in their original condition and packaging. Please tell us why you are returning the items, just for our records. The original purchase price of the goods will be refunded on to the card that was used for their purchase. Sorry, but we can not refund the carriage costs.

This is your right under UK law and, if we do anything else, it’s illegal!

(Please note: This doesn’t apply however if you have chosen to pay via PayPal. Due to the way PayPal works, you are effectively sending the money to us rather than us asking for it so in this instance we will have received payment at the time the order was placed and not when it is ready for dispatch).

We guarantee that we won’t pass your email details on to anyone else

Absolutely not. All your details are treated as strictly confidential. We’re internet users, too, and we know how annoying unsolicited email can be. We wouldn’t risk annoying you by being the cause of it.
